Performance Improvement in Head and Neck Cancer

Abstract

Performance improvement requires establishing a platform to set benchmarks and monitor the quality of care provided through quality indicators and metrics. This has long been recognized as critical to overall quality improvement and more recently, has become federally mandated. Here, we review recent studies evaluating performance in head and neck cancer care, from those spanning all phases of head and neck cancer care to others focused on head and neck surgical performance, including both national and departmental/institutional efforts.

Checkpoint Inhibitors, Palliative Care, or Hospice

Abstract

Purpose

Checkpoint (CTLA-4, PD-1, and PD-L1) inhibitors have changed the face of oncology. A subset of patients enjoys long, gratifying treatment responses. Unfortunately, most patients do not respond even when expressing favorably markers such as PD-L1. Checkpoint inhibitors are largely palliative (though a subset have long-term cancer responses) and as such patient-related outcome measures should be included when evaluating benefits. The purpose of this review is to place checkpoint inhibitor trials within a palliation context. Included is a discussion on potential adverse effects on end-of-life care.

Recent Findings

Pivotal studies have presented efficacy and safety data but we have little published data on quality of life or symptom responses. Extension of life is approximately 2–3 months with some long-term responses in a minority of patients. The cost of checkpoint inhibitors is high for utility (as measured by quality-adjusted life-year saved) and ranges from 81,000 to over 200,000 USD for quality-adjusted life-year saved. Adverse effects were suboptimally reported in multiple studies. Meaningful responses in many trials as defined by the European Society of Medical Oncology are modest.

Summary

Because at least for now, checkpoint inhibitors are used in advanced cancer and largely palliative patients should be seen by palliative specialists, symptoms related to cancer assessed, and advanced directives addressed. Treatment-related autoimmune diseases represent toxicities which oncologists and palliative specialists must understand. This means that palliative care specialists should know about the benefits and adverse effects of these agents. Whether checkpoint inhibitors increase or decrease aggressive care, hospice referrals, and costs at the end of life is yet to be determined.

Living with chronic pain: perceptions of breast cancer survivors

Abstract

Purpose

Breast cancer treatments may lead to chronic pain. For some breast cancer survivors (BCS), this experience can develop into the perception of living with chronic pain. The majority of BCS are postmenopausal and have hormone receptor-positive (HR+) breast cancer requiring aromatase inhibitors (AIs). Neither the prevalence nor risk factors associated with the perception of living with chronic pain among this population are well defined.

Methods

We conducted a cross-sectional survey among postmenopausal, HR+ BCS who previously took or were currently taking AIs. The primary outcome was patients' perception of living with chronic pain over the past 6 months. We measured pain and demographic and clinical variables. Multivariable logistic regression analysis was performed to evaluate risk factors associated with the perception of chronic pain.

Results

Among 1280 participants, 167 (13%) reported having the perception of living with chronic pain before their breast cancer diagnosis; 426 (34%) reported this perception after completion of non-hormonal cancer treatment. Seventy-eight percent of BCSs reported experiencing at least one type of treatment-related pain within the past 7 days, with 23% experiencing at least three types. The most common types of pain were AI-induced musculoskeletal pain (49%) and pain at the surgery or radiation site (31%). Younger age (< 56), BMI > 25, and the perception of living with chronic pain before diagnosis were risk factors associated with the perception of living with chronic pain.

Conclusions

One in three postmenopausal, HR+ BCS considered themselves to be living with chronic pain. Effective interventions to reduce chronic pain are needed.

Long non-coding RNA H19 promotes glucose metabolism and cell growth in malignant melanoma via miR-106a-5p/E2F3 axis

Abstract

Purpose

lncRNA H19 has been considered as an oncogenic lncRNA in many human tumours. In the present study, we identify the role and molecular mechanism of lncRNA H19 in melanoma.

Method

QRT-PCR was used to detect the expression of lncRNA H19 and E2F3 was detected in melanoma tissues. Cell counting kit-8 (CCK8), representative metabolites analysis was used to explore the biological function of lncRNA H19, miR-106a-5p and E2F3 in melanoma cells. Bioinformatics, luciferase reporter assays, MS2-RIP and RNA pull-down assay was used to demonstrate the molecular mechanism of lncRNA H19 in melanoma. We further test the function of lncRNA H19 in vivo though Xenograft tumour assay.

Results

We found that lncRNA H19 was increased in melanoma tissue, and lncRNA H19 was correlated with poor prognosis of melanoma patients. miR-106a-5p acts as a tumour suppressor in melanoma by targeting E2F3. E2F3 affects the melanoma cell glucose metabolism and growth. We also demonstrated that lncRNA H19 may function as the sponge of miR-106a-5p to up-regulate E2F3 expression, and consequently promote the glucose metabolism and growth of melanoma.

Conclusions

This result elucidates a new mechanism for lncRNA H19 in melanoma development and provides a survival indicator and potential therapeutic target for melanoma patients.

Tibolone and risk of gynecological hormone sensitive cancer

Abstract

Risk of ovarian cancer with hormone therapy is associated with use of both unopposed estrogen therapy and combined estrogen-progestin therapy, whereas for endometrial cancer addition of continuous progestin decreases the estrogen induced increased risk. Less is known about risk with use of tibolone; a synthetic steroid with estrogenic, progestagenic, and androgenic properties. We assessed these associations in a prospective cohort study, including all Danish women 50–79 years of age and followed 1995–2009. National Danish Registers captured individually updated exposure information, cancer cases including histology and confounding factors. Poisson regression analyses provided multiple adjusted incidence rate ratio's (IRR).

More than 900,000 women were followed for 9.8 years on average; 4,513 were diagnosed with ovarian cancer and 6,202 with endometrial cancer.

Compared to women never on postmenopausal hormone therapy, current users of tibolone had an increased IRR for ovarian cancer (1.42(95% confidence interval [CI], 1.01-2.00) and serous ovarian tumors (2.21(95%CI 1.48-3.32)). The risk increased with duration of use, particularly for serous ovarian tumors.

Compared to never users, the IRR of endometrial cancer was 3.56(95%CI 2.94-4.32) among current users of tibolone and 3.80(95%CI 3.08–4.69) of Type 1 endometrial cancer. The steepest risk increase with duration of use was for Type I tumors.

In conclusion, tibolone is associated with increased risk for ovarian and endometrial cancer overall; and particular the risk of serous ovarian tumors and Type 1 endometrial cancer. Because the associations are stronger with increasing durations of use - and for hormone sensitive tumors -the results seem indicative of causality. This article is protected by copyright.
