In Chemotherapy for Lung Cancer, Sometimes Less is More

Efficacy of Vinorelbine Monotherapy as Third- or Further-Line Therapy in Patients with Advanced Non-Small-Cell Lung Cancer

BACKGROUND

The survival rate of patients with lung cancer has increased significantly over the years, but there has been no further progress in third- or fourth-line therapy. We investigated the efficacy and tolerability of monotherapy with weekly vinorelbine, a semi-synthetic vinca alkaloid, in advanced non-small-cell lung cancer (NSCLC) patients who had previously been treated several times.

METHODS

In all, 159 NSCLC patients who received vinorelbine monotherapy as third- or further-line therapy between January 2008 and July 2017 were included in this study. Patients received vinorelbine intravenously at a dose of 25-30 mg/m2/week.

RESULTS

Their mean age was 62.4 years. The histologic types of tumor were adenocarcinoma (50.9%), squamous cell carcinoma (42.8%), and others (6.2%). The overall response rate was 19.5% (31/159). The median progression-free survival (PFS) was 3.0 months (95% confidence interval [CI] 2.5-3.5 months), and the median overall survival (OS) after vinorelbine use was 7.6 months (95% CI 6.2-9.0 months). Vinorelbine therapy showed significantly higher efficacy in patients with adenocarcinoma, and these patients had a longer PFS than patients with other types of cancer. Patients who received vinorelbine as fifth- or further-line treatment had a higher response rate and longer PFS and OS than those who received vinorelbine as third- or fourth-line treatment.

CONCLUSIONS

Weekly vinorelbine monotherapy may be a feasible therapeutic option for patients with heavily treated, advanced NSCLC, particularly lung adenocarcinoma.

Chemotherapy Use, End-of-Life Care, and Costs of Care Among Patients Diagnosed With Stage IV Pancreatic Cancer

CONTEXT

For patients with metastatic cancer and limited life expectancy, potential benefits of chemotherapy must be balanced against harms to quality of life near death and increased out-of-pocket costs of care.

OBJECTIVES

To evaluate the association between chemotherapy use by patients with Stage IV pancreatic cancer and health care use and Medicare and out-of-pocket costs in the last 30 days of life.

METHODS

We conducted a retrospective cohort study of 3825 patients aged 66 years or older when diagnosed with Stage IV pancreatic cancer in 2006-2011, using the linked Surveillance, Epidemiology, and End Results-Medicare data. Using a propensity score matched sample, we examined associations between initiation of chemotherapy shortly after the metastatic diagnosis (and secondarily, continued chemotherapy use in the last 30 days of life) and health care use and costs (both Medicare payment and patient out-of-pocket costs) in the last 30 days of life.

RESULTS

Chemotherapy use was associated with increased rates of hospital admissions (45.0% vs. 29.2%, P < 0.001), emergency department visits (41.3% vs. 27.2%, P < 0.001), and death in a hospital (14.2% vs. 9.1%, P < 0.001); fewer days in hospice care (11.5 days vs. 15.7 days, P < 0.001); and more than 50% increase in patient out-of-pocket costs for care ($1311.5 vs. $841.0, P < 0.001) in the last 30 days of life. Among patients who initiated chemotherapy, more stark differences in these outcomes were found by whether patients received chemotherapy in the last 30 days of life.

CONCLUSION

Chemotherapy use among older patients diagnosed with metastatic pancreatic cancer was associated with substantially increased use of health care and higher patient out-of-pocket costs near death.

The TEAM Approach to Improving Oncology Outcomes by Incorporating Palliative Care in Practice

Palliative care (PC) concurrent with usual oncology care is now the standard of care that is recommended for any patient with advanced cancer to begin within 8 weeks of diagnosis on the basis of evidence-driven national clinical practice guidelines; however, there are not enough interdisciplinary palliative care teams to provide such care. How and what can an oncology office incorporate into usual care, borrowing the tools used in PC randomized clinical trials (RCTs), to improve care for patients and their caregivers? We reviewed the multiple RCTs for common practical elements and identified methods and techniques that oncologists can use to deliver some parts of concurrent interdisciplinary PC. We recommend the standardized assessment of patient-reported outcomes, including the evaluation of symptoms with such tools as the Edmonton or Memorial Symptom Assessment Scales, spirituality with the FICA Spiritual History Tool or similar questions, and psychosocial distress with the Distress Thermometer. All patients should be assessed for how they prefer to receive information, their current understanding of their situation, and if they have considered some advance care planning. Approximately 1 hour of additional time with the patient is required each month. If the oncologist does not have established ties with spiritual care and social work, he or she should establish these relationships for counseling as required. Caregivers should be asked about coping and support needs. Oncologists can adapt PC techniques to achieve results that are similar to those in the RCTs of PC plus usual care compared with usual care alone. This is comparable to using data from RCTs of trastuzamab or placebo, adopting what was used in the RCTs without modification or dilution.

Integration of Palliative Care Into Standard Oncology Care: American Society of Clinical Oncology Clinical Practice Guideline Update

Purpose To provide evidence-based recommendations to oncology clinicians, patients, family and friend caregivers, and palliative care specialists to update the 2012 American Society of Clinical Oncology (ASCO) provisional clinical opinion (PCO) on the integration of palliative care into standard oncology care for all patients diagnosed with cancer. Methods ASCO convened an Expert Panel of members of the ASCO Ad Hoc Palliative Care Expert Panel to develop an update. The 2012 PCO was based on a review of a randomized controlled trial (RCT) by the National Cancer Institute Physicians Data Query and additional trials. The panel conducted an updated systematic review seeking randomized clinical trials, systematic reviews, and meta-analyses, as well as secondary analyses of RCTs in the 2012 PCO, published from March 2010 to January 2016. Results The guideline update reflects changes in evidence since the previous guideline. Nine RCTs, one quasiexperimental trial, and five secondary analyses from RCTs in the 2012 PCO on providing palliative care services to patients with cancer and/or their caregivers, including family caregivers, were found to inform the update. Recommendations Inpatients and outpatients with advanced cancer should receive dedicated palliative care services, early in the disease course, concurrent with active treatment. Referral of patients to interdisciplinary palliative care teams is optimal, and services may complement existing programs. Providers may refer family and friend caregivers of patients with early or advanced cancer to palliative care services.

Systemic Therapy for Stage IV Non-Small-Cell Lung Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update

PURPOSE

To provide evidence-based recommendations to update the American Society of Clinical Oncology guideline on systemic therapy for stage IV non-small-cell lung cancer (NSCLC).

METHODS

An Update Committee of the American Society of Clinical Oncology NSCLC Expert Panel based recommendations on a systematic review of randomized controlled trials from January 2007 to February 2014.

RESULTS

This guideline update reflects changes in evidence since the previous guideline.

RECOMMENDATIONS

There is no cure for patients with stage IV NSCLC. For patients with performance status (PS) 0 to 1 (and appropriate patient cases with PS 2) and without an EGFR-sensitizing mutation or ALK gene rearrangement, combination cytotoxic chemotherapy is recommended, guided by histology, with early concurrent palliative care. Recommendations for patients in the first-line setting include platinum-doublet therapy for those with PS 0 to 1 (bevacizumab may be added to carboplatin plus paclitaxel if no contraindications); combination or single-agent chemotherapy or palliative care alone for those with PS 2; afatinib, erlotinib, or gefitinib for those with sensitizing EGFR mutations; crizotinib for those with ALK or ROS1 gene rearrangement; and following first-line recommendations or using platinum plus etoposide for those with large-cell neuroendocrine carcinoma. Maintenance therapy includes pemetrexed continuation for patients with stable disease or response to first-line pemetrexed-containing regimens, alternative chemotherapy, or a chemotherapy break. In the second-line setting, recommendations include docetaxel, erlotinib, gefitinib, or pemetrexed for patients with nonsquamous cell carcinoma; docetaxel, erlotinib, or gefitinib for those with squamous cell carcinoma; and chemotherapy or ceritinib for those with ALK rearrangement who experience progression after crizotinib. In the third-line setting, for patients who have not received erlotinib or gefitinib, treatment with erlotinib is recommended. There are insufficient data to recommend routine third-line cytotoxic therapy. Decisions regarding systemic therapy should not be made based on age alone.

FLLL12 induces apoptosis in lung cancer cells through a p53/p73-independent but death receptor 5-dependent pathway

Unlike chemotherapy drugs, the safety of natural compounds such as curcumin has been well established. However, the potential use of curcumin in cancer has been compromised by its low bioavailability, limited tissue distribution and rapid biotransformation leading to low in vivo efficacy. To circumvent these problems, more potent and bioavailable analogs have been synthesized. In the current study, we investigated the mechanism of anti-tumor effect of one such analog, FLLL12, in lung cancers. IC50 values measured by sulforhodamine B (SRB) assay at 72 h and apoptosis assays (annexin V staining, cleavage of PARP and caspase-3) suggest that FLLL12 is 5-10-fold more potent than curcumin against a panel of premalignant and malignant lung cancer cell lines, depending on the cell line. Moreover, FLLL12 induced the expression of death receptor-5 (DR5). Ablation of the expression of the components of the extrinsic apoptotic pathway (DR5, caspase-8 and Bid) by siRNA significantly protected cells from FLLL12-induced apoptosis (p < 0.05). Analysis of mRNA expression revealed that FLLL-12 had no significant effect on the expression of DR5 mRNA expression. Interestingly, inhibition of global phosphatase activity as well as protein tyrosine phosphatases (PTPs), but not of alkaline phosphatases, strongly inhibited DR5 expression and significantly inhibited apoptosis (p < 0.05), suggesting the involvement of PTPs in the regulation of DR5 expression and apoptosis. We further showed that the apoptosis is independent of p53 and p73. Taken together, our results strongly suggest that FLLL12 induces apoptosis of lung cancer cell lines by posttranscriptional regulation of DR5 through activation of protein tyrosine phosphatase(s).
