At-home cancer screening: a solution for China and other developing countries with a large population and limited number of healthcare practitioners

Abstract

Five-year survival rate for patients with all cancers combined, in China, is only 30.9%, which is much lower than those in developed countries. The three main reasons for the low cancer curative rates in China include differences in the spectrum of cancer types, in early detection rates, and in the percentage of cancer patients receiving standardized treatment between China and developed countries. The most important mechanism for improving the curative rate is to improve early detection rates of major cancers in China using novel and affordable technologies that can be operated at home by the patients themselves. This attempt could be helpful in setting up a practical example for other developing countries with limited medical resources and a limited number of healthcare practitioners.

Comparison of recommendations for screening mammography using CISNET models

BACKGROUND

Currently, there are several different recommendations for screening mammography from major national health care organizations, including: 1) annual screening at ages 40 to 84 years; 2) screening annually at ages 45 to 54 years, then biennially at ages 55 to 79 years; and 3) biennial screening at ages 50 to 74 years.

METHODS

Mean values of six Cancer Intervention and Surveillance Modeling Network (CISNET) models were used to compare these three screening mammography recommendations in terms of benefits and risks.

RESULTS

Mean mortality reduction was greatest with the recommendation of annual screening at ages 40 to 84 years (39.6%), compared with the hybrid recommendation of screening annually at ages 45 to 54 years, then biennially at ages 55 to 79 years (30.8%), and the recommendation of biennial screening at ages 50 to 74 years (23.2%). For a single-year cohort of US women aged 40 years, assuming 100% compliance, more breast cancers deaths would be averted over their lifetime with annual screening starting at age 40 (29,369) than with the hybrid recommendation (22,829) or biennial screening ages 50-74 (17,153 based on 2009 CISNET estimates, 15,599 based on 2016 CISNET estimates). To achieve the greatest mortality benefit, this single-year cohort of women would have the greatest total number of screening mammograms, benign recalls, and benign biopsies performed over the course of screening by following annual screening starting at age 40 years (90.2 million, 6.8 million, and 481,269, respectively) than by following the hybrid recommendation (49.0 million, 4.1 million, and 286,288, respectively) or biennial screening at ages 50 to 74 years (27.3 million, 2.3 million, and 162,885, respectively).

CONCLUSION

CISNET models demonstrate that the greatest mortality reduction is achieved with annual screening of women starting at age 40 years. Cancer 2017. © 2017 American Cancer Society.

On assessing the effect of breast cancer screening schemes

Our goal should be to provide truthful, balanced information so that women can make informed choices about when to start screening for breast cancer. A woman who is making a decision about screening is more interested in her personal chances of benefit and risk of harm and is less interested in the benefits to the population.

Tubo-ovarian abscess infected by Salmonella typhi

We report a case of a tubo-ovarian abscess infected with Salmonella enterica serotype typhi. A 19-year-old Nepalese woman presented to a hospital in Kathmandu with lower abdominal pain, constipation, fever and a non-healing, suppurative surgical wound from an emergency caesarian section performed 2 months previously at 37 weeks of pregnancy. She also had an exploratory laparotomy for an appendix perforation with peritonitis at 25 weeks of gestation. Her wound infection did not respond to cloxacillin and she had an exploratory laparotomy, and a tubo-ovarian abscess was found from which S. typhi was isolated. She had a bilateral salpingo-oophorectomy and responded to 14 days of chloramphenicol. A tubo-ovarian abscess is a rare complication of enteric fever.

Solitary biceps muscle metastasis from breast cancer

Although direct muscle invasion by carcinoma is well recognised, skeletal muscle metastases are rare. Breast cancer very rarely metastasises to skeletal muscles. We present a case of breast cancer that metastasised to the biceps muscle. The woman developed breast cancer in 1990 and then developed axillary subcutaneous metastasis in 2001. In 2015, she presented with pain in the left forearm extending to the hand. Initial imaging showed no abnormalities, but the positron emission tomography-CT scanning revealed a hot spot in the left biceps muscle. Additionally, the nerve conduction study showed feature of carpal tunnel syndrome. The hot spot was deemed inconclusive in the view of normal CT and MRI scans, and the patient was treated with carpal tunnel decompression. A few months later, the patient developed a lump in the left biceps muscle, which appeared to be a metastatic lesion from her primary breast cancer. The patient was treated with radiotherapy and responded satisfactorily.

Topical ayurvedic ointment-induced chemical injury presenting as bilateral acute keratitis

A 40-years-old female patient was referred to the cornea clinic as a probable case of bilateral keratitis. The patient had a history of headache followed by acute onset of redness, pain and discharge from both eyes for 15 days. The patient was diagnosed as bilateral keratitis by the first contact physician and was started on topical antibiotics, cycloplegics and lubricating eye-drops. At presentation, both eyes had visual acuity of perception of light, conjunctival congestion, limbal blanching, diffuse corneal oedema and epithelial defect. A detailed history revealed application of Vicks VapoRub [topical ayurvedic analgesic which contains (per 100 g of product) menthol (2.82 g), camphor (5.25 g) and eucalyptol (1.49 mL) and excipients include thymol (0.1 g), turpentine oil (5.57 mL), nutmeg oil (0.54 mL), cedar wood oil and petrolatum)] on the forehead and eyelids for headache several times over 2–3 days before the onset. The patient further confirmed the accidental application of the ointment in the eyes. A provisional diagnosis of acute chemical injury with Vicks VapoRub was made and treatment with topical antibiotic, cycloplegic, steroid, lubricant and vitamin C was started. On follow-up, both eyes showed gradual resolution of corneal oedema and epithelial defect. Visual acuity improved in the left eye to 6/60 with no change in right eye due to corneal haze.

Vermiform appendix within incisional hernia

The vermiform appendix (whether inflamed or not) within a hernia is very rare occurrence. We present the unprecedented case of a normal appendix found within a Pfannenstiel incisional hernia. A diagnostic laparoscopy was performed as appendicitis was suspected. However, the tip of a normal appendix was visualised within a previous Pfannenstiel incision. Laparoscopic appendicectomy was carried successfully and the patient was discharged. The patient later returned for a successful elective laparoscopic incisional hernia repair.

Regulatory T cell subsets in patients with medulloblastoma at diagnosis and during standard irradiation and chemotherapy (PBTC N-11)

Abstract

Background

We evaluated circulating levels of immunosuppressive regulatory T cells (Tregs) and other lymphocyte subsets in patients with newly diagnosed medulloblastoma (MBL) undergoing surgery compared to a control cohort of patients undergo craniectomy for correction of Chiari malformation (CM) and further determined the impact of standard irradiation and chemotherapy on this cell population.

Methods

Eligibility criteria for this biologic study included age 4–21 years, patients with CM undergoing craniectomy (as non-malignant surgical controls) and receiving dexamethasone for prevention of post-operative nausea, and those with newly diagnosed posterior fossa tumors (PFT) undergoing surgical resection and receiving dexamethasone as an anti-edema measure. Patients with confirmed MBL were also followed for longitudinal blood collection and analysis during radiotherapy and chemotherapy.

Results

A total of 54 subjects were enrolled on the study [22-CM, 18-MBL, and 14-PFT]. Absolute number and percentage Tregs (defined as CD4+CD25+FoxP3+CD127low/−) at baseline were decreased in MBL and PFT compared to CM [p = 0.0016 and 0.001, respectively). Patients with MBL and PFT had significantly reduced overall CD4+ T cell count (p = 0.0014 and 0.0054, respectively) compared to those with CM. Radiation and chemotherapy treatment in patients with MBL reduced overall lymphocyte counts; however, within the CD4+ T cell compartment, Tregs increased during treatment but gradually declined post therapy.

Conclusions

Our results demonstrate that patients with MBL and PFT exhibit overall reduced CD4+ T cell counts at diagnosis but not an elevated proportion of Tregs. Standard treatment exacerbates lymphopenia in those with MBL while enriching for immunosuppressive Tregs over time.

Autophagy inhibits high glucose induced cardiac microvascular endothelial cells apoptosis by mTOR signal pathway

Abstract

Cardiac microvascular endothelial cells (CMECs) dysfunction is an important pathophysiological event in the cardiovascular complications induced by diabetes. However, the underlying mechanism is not fully clarified. Autophagy is involved in programmed cell death. Here we investigated the potential role of autophagy on the CMECs injury induced by high glucose. CMECs were cultured in normal or high glucose medium for 6, 12 and 24 h respectively. The autophagy of CMECs was measured by green fluorescence protein (GFP)-LC3 plasmid transfection. Moreover, the apoptosis of CMEC was determined by flow cytometry. Furthermore, 3-Methyladenine (3MA), ATG7 siRNA and rapamycin were administrated to regulate the autophagy state. Moreover, Western blotting assay was performed to measure the expressions of Akt, mTOR, LC3 and p62. High glucose stress decreased the autophagy, whereas increased the apoptosis in CMECs time dependently. Meanwhile, high glucose stress activated the Akt/mTOR signal pathway. Furthermore, autophagy inhibitor, 3-MA and ATG7 siRNA impaired the autophagy and increased the apoptosis in CMECs induced by high glucose stress. Conversely, rapamycin up-regulated the autophagy and decreased the apoptosis in CMECs under high glucose condition. Our data provide evidence that high glucose directly inhibits autophagy, as a beneficial adaptive response to protect CMECs against apoptosis. Furthermore, the autophagy was mediated, at least in part, by mTOR signaling.

Ovarian cancer recurrence and early detection: may HE4 play a key role in this open challenge? A systematic review of literature

Abstract

Despite the improvement in overall survival for ovarian cancer (OC) patients, a fraction of patients with advanced-stage disease fails to respond to primary therapy and relapses in 70% of cases. For this reason, new predictive and monitoring tools are needed to identify OC recurrence and new biomarkers were studied, among which human epididymis 4 (HE4), primarily expressed in the reproductive and respiratory tracts, is one of the most promising, reporting a good sensitivity and specificity in detecting OC, overcoming the traditional role of carbohydrate antigen 125 (CA-125). In this review, we aim to discuss the latest evidence reported in the literature about the use of HE4 to monitor ovarian cancer treatment and to detect OC recurrence. We searched MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, Web of Science, SCOPUS, congress abstracts, and Grey literature (Google Scholar; British Library) from January 1952 to June 2017. The search identified seven papers in line with eligibility criteria for this systematic review; all of them demonstrated a good performance of HE4 in OC recurrence. The challenge to anticipate the diagnosis of OC recurrence and to translate this early diagnosis of relapse in a survival and quality of life improvement is still open, and as reported in this review, HE4 may play a key role in this scenario. More studies are needed to validate and reinforce the role of HE4 in ovarian cancer recurrence and in its early detection.

Acquired temozolomide resistance in human glioblastoma cell line U251 is caused by mismatch repair deficiency and can be overcome by lomustine

Abstract

Purpose

Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor in adults. While the alkylating agent temozolomide (TMZ) has prolonged overall survival, resistance evolution represents an important clinical problem. Therefore, we studied the effectiveness of radiotherapy and CCNU in an in vitro model of acquired TMZ resistance.

Methods

We studied the MGMT-methylated GBM cell line U251 and its in vitro derived TMZ-resistant subline, U251/TMZ-R. Cytotoxicity of TMZ, CCNU, and radiation was tested. Both cell lines were analyzed for MGMT promotor status and expression of mismatch repair genes (MMR). The influence of MMR inhibition by cadmium chloride (CdCl2) on the effects of both drugs was evaluated.

Results

During the resistance evolution process in vitro, U251/TMZ-R developed MMR deficiency, but MGMT status did not change. U251/TMZ-R cells were more resistant to TMZ than parental U251 cells (cell viability: 92.0% in U251/TMZ-R/69.2% in U251; p = 0.032) yet more sensitive to CCNU (56.4%/80.8%; p = 0.023). The effectiveness of radiotherapy was not reduced in the TMZ-resistant cell line. Combination of CCNU and TMZ showed promising results for both cell lines and overcame resistance. CdCl2-induced MMR deficiency increased cytotoxicity of CCNU.

Conclusion

Our results confirm MMR deficiency as a crucial process for resistance evolution to TMZ. MMR-deficient TMZ-resistant GBM cells were particularly sensitive to CCNU and to combined CCNU/TMZ. Effectiveness of radiotherapy was preserved in TMZ-resistant cells. Consequently, CCNU might be preferentially considered as a treatment option for recurrent MGMT-methylated GBM and may even be suitable for prevention of resistance evolution in primary treatment.

A Successfully Treated Case of Gastrointestinal Stromal Tumor Causing Severe Anemia and Localized Peritonitis Showing Angina Pectoris Resulting in Watershed Cerebral Infarction

Ischemic stroke following acute myocardial infarction is a rare but a serious complication. Because the pathophysiology of stroke is dynamic, it is often hard to identify the cause of stroke. Here, we present the case of a 75-year-old man with ischemic stroke following angina pectoris caused by severe anemia and localized peritonitis due to gastrointestinal stromal tumor of small intestine. On admission, he showed consciousness disturbance, fever, and left hemiplegia. The electrocardiogram on admission showed ST-segment depression in V2 to V6 which was normalized 4 hours later. The ultrasound cardiogram showed the mild hypokinesis in the apical portion of left ventricle which was also normalized later. The magnetic resonance imaging and angiography showed ischemic stroke in watershed area between right anterior and middle cerebral arteries area and stenosis of distal portion of right middle cerebral artery. The computed tomography of abdomen showed a mass of small intestine. We decided to perform curative surgery after transfusion and successfully resected the mass of the small intestine, which was revealed to be a gastrointestinal stromal tumor (GIST). This is a successfully treated case of GIST in which the complicated pathophysiology of watershed cerebral infarction following angina pectoris might be clearly revealed.

A geographic information system-based method for estimating cancer rates in non-census defined geographical areas

Abstract

Purpose

To address locally relevant cancer-related health issues, health departments frequently need data beyond that contained in standard census area-based statistics. We describe a geographic information system-based method for calculating age-standardized cancer incidence rates in non-census defined geographical areas using publically available data.

Methods

Aggregated records of cancer cases diagnosed from 2009 through 2013 in each of Chicago's 77 census-defined community areas were obtained from the Illinois State Cancer Registry. Areal interpolation through dasymetric mapping of census blocks was used to redistribute populations and case counts from community areas to Chicago's 50 politically defined aldermanic wards, and ward-level age-standardized 5-year cumulative incidence rates were calculated.

Results

Potential errors in redistributing populations between geographies were limited to <1.5% of the total population, and agreement between our ward population estimates and those from a frequently cited reference set of estimates was high (Pearson correlation r = 0.99, mean difference = −4 persons). A map overlay of safety-net primary care clinic locations and ward-level incidence rates for advanced-staged cancers revealed potential pathways for prevention.

Conclusions

Areal interpolation through dasymetric mapping can estimate cancer rates in non-census defined geographies. This can address gaps in local cancer-related health data, inform health resource advocacy, and guide community-centered cancer prevention and control.

Can complementary medicine increase adherence to chemotherapy dosing protocol? A controlled study in an integrative oncology setting

Abstract

Context and objectives

The impact of complementary and integrative medicine (CIM) on adherence to chemotherapy regimens is unclear. We explored the effect of patient-tailored CIM treatments on the relative dose intensity (RDI) of chemotherapy among patients with breast and gynecological cancer.

Methods

Chemotherapy-treated patients with breast or gynecological cancer were referred by their oncology healthcare professional to a CIM treatment program. Adherence to integrative care (AIC) was defined as ≥4 CIM treatments, with ≤30 days between each treatment. Relative dose intensity (RDI) of chemotherapy was compared between CIM-treated patients and controls, and among adherence sub-groups.

Results

RDI was calculated for 106-treated patients (62 AIC) and 75 controls. Baseline-to-6-week RDI values were similar in both study arms, with a lower % RDI <1.0 among controls at 12 weeks (47 vs. 57.5%; P = 0.036). Adherence sub-groups had similar RDI values, though at 6 weeks, the AIC group had lower % RDI <1.0 (33.9 vs. 54.5%, P = 0.046). Total administered medication dose/planned dose was higher in the AIC group at 6 weeks for paclitaxel (82%/50%, P = 0.025) and carboplatin (87%/67%, P = 0.028), with no difference in cytoxan/adriamycin dosages.

Conclusion

A patient-tailored CIM program for patients with breast or gynecological cancer may be associated with a lower percentage of reduced RDI at 6 weeks, this in a sub-group of patients with higher adherence to CIM, and for specific chemotherapy agents, though this benefit did not persist after 12 weeks. Further research is needed to better understand the impact of CIM in cancer care.

Awakening immunity against cancer: a 2017 primer for clinicians

Abstract

Cancer immunotherapy has finally joined the pillars of cancer treatment—surgery, radiation, chemotherapy, hormonal therapy, and targeted therapy—in improving cancer patient lives. In the last 5 years, the development of immune checkpoint inhibitor and T cell therapy, particularly chimeric antigen receptor (CAR) T-cell therapy, has been remarkable for the speed, scale, and number of drug approvals. Still, these treatments may also bring unusual adverse effects and clinical outcomes including unprecedented long-term survival. Interrogating the tumor microenvironment and identifying better biomarkers hold the key to improving cancer immunotherapies. CAR T-cell therapy has dramatic effect on leukemias and lymphomas with significant cure rates, but has yet to show comparable effect on solid tumors. Cutting-edge technology will improve both processing and clinical effect of such therapies. Asia has the largest, most rapidly aging population and the largest number of cancer patients in the world. Research and development and clinical trial conduct of cancer immunotherapy in Asia remain nascent, but should be a crucial priority.

Granulomatosis with Polyangiitis with Myocarditis and Ventricular Tachycardia

Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a pulmonary-renal syndrome affecting small and medium sized blood vessels. The disease has a prevalence in studies ranging from 3 to 15.7 cases per 100,000, with a noted increasing incidence and prevalence in more recent studies. Pulmonary manifestations include hemorrhage, lung cavitary lesions, and pulmonary fibrosis. Within the kidney, GPA is known to cause rapidly progressive pauci-immune crescentic glomerulonephritis. Rare and severe cardiovascular manifestations include pericarditis, arrhythmias, myocarditis, and aortic valve disease. Our patient is a 43-year-old female with typical pulmonary and renal lesions from GPA and also acute myocarditis, multiple episodes of ventricular tachycardia, and a severe reactive thrombocytosis.

Urinary biomarkers in prostate cancer detection and monitoring progression

Prostate cancer (CaP) is the most common cancer in men and the second leading cause of cancer deaths in males in Australia. Although serum prostate-specific antigen (PSA) has been the most widely used biomarker in CaP detection for decades, PSA screening has limitations such as low specificity and potential association with over-diagnosis. Current biomarkers used in the clinic are not useful for the early detection of CaP, or monitoring its progression, and have limited value in predicting response to treatment. Urine is an ideal body fluid for the detection of protein markers of CaP and is emerging as a potential source for biomarker discovery. Gene-based biomarkers in urine such as prostate cancer antigen-3 (PCA3), and genes for transmembrane protease serine-2 (TMPRSS2), and glutathione S-transferase P (GSTP1) have been developed and evaluated in the past decades. Among these biomarkers, urinary PCA3 is the only one approved by the FDA in the USA for clinical use. The study of urine microRNAs (miRNAs) is another burgeoning area for investigating biomarkers to achieve a pre-biopsy prediction of CaP to contribute to early detection. The development of mass spectrometry (MS)-based proteomic techniques has sparked new searches for novel protein markers for many diseases including CaP.Urinary biomarkers for CaP represent a promising alternative or an addition to traditional biomarkers. Future success in biomarker discovery will rely on collaboration between clinics and laboratories. In addition, research efforts need to be moved from biomarker discovery to validation in a large cohort or separate population and translation of these findings to clinical practice. In this review, we discuss urine as a potential source for CaP biomarker discovery, summarise important genetic urine biomarkers in CaP and focus on MS-based proteomic approaches as well as other recent developments in quantitative techniques for CaP urine biomarker discovery.
