The anticancer effect of statins in obese esophageal cancer patients undergoing esophagectomy.

BACKGROUND: In addition to treating hyperlipidemia and atherosclerosis, statins have demonstrated anti-inflammatory and antitumor activity in various cancers. We evaluate this effect in esophageal cancer patients undergoing esophagectomy. METHODS: Esophageal cancer patients undergoing esophagectomy at Roswell Park Comprehensive Cancer Center between March 2007 and December 2015 were included. Association between presurgery statin use and relevant variables with overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) was analyzed using Cox hazards. Survival analyses were independently performed for body mass index (BMI)-based subgroups. RESULTS: There was no significant association between statin use and outcomes overall. However, in subgroup analysis, there was significant association between statin use and outcomes in patients with BMI ≥ 30. Multivariable analysis in obese patients demonstrated the association of statins with improved OS (hazard ratio [HR]: 0.46, p = 0.025), DSS (HR: 0.39, p = 0.015), and RFS (HR: 0.38, p = 0.022). The only other variable significantly associated with all three outcome measures was stage. CONCLUSIONS: Statin use is associated with improved OS, DSS, and RFS of obese patients in resected esophageal cancer. BMI could be investigated as a biomarker for adjunctive statin use in future studies.

Two- Versus Four-Times Weekly Acupuncture-Like Transcutaneous Electrical Nerve Stimulation for Treatment of Radiation-Induced Xerostomia: A Pilot Study.

Background: Xerostomia occurs in the majority of patients undergoing chemoradiation therapy for head and neck cancer (HNC). Acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) treatment has been studied as an encouraging modality to improve salivary function and related symptoms. The purpose of this study was to compare ALTENS treatment by using a four-times weekly schedule for 6 weeks versus a twice-weekly schedule for 12 weeks with a validated xerostomia scale at 15 months from the start of ALTENS treatment. Materials and Methods: This single-center randomized study was conducted in 30 patients treated with radiotherapy with or without chemotherapy for HNC between 2014 and 2017, who had at least grade 1 or 2 symptomatic dry mouth (xerostomia) according to CTEP NCI Common Terminology Criteria for Adverse Events (CTCAE version 4.0). These patients were randomly assigned to receive ALTENS four-times weekly for 6 weeks or two-times weekly for 12 weeks. The University of Michigan 15-item Xerostomia-related Quality of Life Scale (XeQoLS) was administered at 6, 9, 15, and 21 months from the start of ALTENS treatment. A random-effects generalized linear model was used to model the overall XeQoLS score at the 15-month endpoint; adjusted for a random time effect, a fixed treatment arm, and interaction of time and treatment. Comparison between arms was based on a 0.05 nominal significance level. Results: XeQoLS decreased for all patients (although not statistically for each arm) from a mean of 22 and 21 at baseline (in the four times per week and twice weekly arms) to 12 in both arms at 15 months, with no difference between arms (p = 0.68). There were no attributable grade 1-3 adverse events. Arms were balanced for age, gender, race, and baseline xerostomia. Conclusions: This study demonstrates that both ALTENS regimens are safe, well tolerated, and appear to be equally effective. We now routinely make ALTENS units available for home use.

Role of Adjuvant Chemotherapy in Pulmonary Carcinoids: An NCDB Analysis.

BACKGROUND/AIM: Typical carcinoids (TC) and atypical carcinoids (AC) are rare diseases. A paucity of randomized studies and disagreements among various guidelines makes the management challenging. PATIENTS AND METHODS: Using codes for TC (8240) and AC (8249) in the National Cancer Database (NCDB), all surgically resected cases from 2004-2014 were included to evaluate the need for adjuvant chemotherapy. RESULTS: A total of 6,673 cases were included, 88% were TCs and 12% were ACs. From 2004 to 2014, the proportion of TCs went up from 1.3% to 1.8% and ACs from 0.1% to 0.3% of all lung malignancies. TC patients did well with surgery alone in all stages. AC patients with stage I [5-year overall survival (OS) - 84% vs. 52%; S vs. S+CT] and stage II disease (5-year OS - 81% vs. 55%; S vs. S+CT) showed better OS trend with surgery alone, while stage III patients showed some benefit with the use of adjuvant chemotherapy (5-year OS - 46% vs. 54%; S vs. S+CT). These results supported the National Comprehensive Cancer Network (NCCN) guidelines. CONCLUSION: No benefit was seen from adjuvant chemotherapy in TCs. While the adjuvant therapy may add benefit in stage III AC, the numbers are small and did not reach statistical significance.

Hospice utilization and end-of-life care in metastatic breast cancer patients at a comprehensive cancer center.

BACKGROUND: Metastatic breast cancer patients have many options for therapy and may be at risk for late or absent hospice referrals, which make meaningful improvements in symptoms and quality of life difficult to achieve. OBJECTIVE: We aimed to examine hospice utilization, status of patients on admission, and quality of care of patients treated for metastatic breast cancer from 1999 to 2010 at a National Cancer Institute (NCI)-designated comprehensive cancer center located in Western New York. METHODS: We conducted a retrospective database review that identified 182 patients with deaths resulting from breast cancer who were eligible for services through a local not-for-profit hospice. Patients with metastatic breast cancer were matched to the hospice database for information on hospice utilization and quality measures. Date of last chemotherapy, medication use, documentation of advance directive and palliative care discussions, and place of death were collected through chart abstraction. RESULTS: One-third (33%) of metastatic breast cancer patients treated at the cancer institute during the study period died without a hospice referral. Only 7% of patients who died without a hospice referral had a documented discussion of palliative care as an option by the oncology team (p < 0.001). Those patients referred to hospice were significantly more likely to have an advance directive and to die at home. Patients with a longer duration of metastatic cancer were at risk for late referral. CONCLUSIONS: Efforts to enhance end-of-life (EOL) discussions and earlier referral to palliative care and hospice for patients with metastatic breast cancer are critical to improved patient care.

Serum vitamin D metabolites in colorectal cancer patients receiving cholecalciferol supplementation: correlation with polymorphisms in the vitamin D genes.

Cholecalciferol (D(3)) supplementation results in variable increases in serum 25(OH)D(3) levels, however, the influence of genetic polymorphisms on these variable responses is unclear. We measured serum 25(OH)D(3), 24,25(OH)(2)D(3), 1,25(OH)2D(3) and VDBP levels in 50 colorectal cancer (CRC) patients before and during 2,000 IU daily oral D(3) supplementation for six months and in 263 archived CRC serum samples. Serum PTH levels and PBMC 24-OHase activity were also measured during D(3) supplementation. TagSNPs in CYP2R1, CYP27A1, CYP27B1, CYP24A1, VDR, and GC genes were genotyped in all patients, and the association between these SNPs and serum vitamin D(3) metabolites levels before and after D(3) supplementation was analyzed. The mean baseline serum 25(OH)D(3) level was less than 32 ng/mL in 65 % of the 313 CRC patients. In the 50 patients receiving D(3) supplementation, serum levels of 25(OH)D(3) increased (p = 0.008), PTH decreased (p = 0.036) and 24,25(OH)(2)D(3), 1,25(OH)(2)D(3), VDBP levels and PBMC 24-OHase activity were unchanged. GC SNP rs222016 was associated with high 25(OH)D(3) and 1,25(OH)(2)D(3) levels at baseline while rs4588 and rs2282679 were associated with lower 25(OH)D(3) and 1,25(OH)(2)D(3) levels both before and after D(3) supplementation. CYP2R1 rs12794714 and rs10500804 SNPs were significantly associated with low 25(OH)D(3) levels after supplementation but not with baseline 25(OH)D(3). Our results show that D(3) supplementation increased 25(OH)D(3) levels in all patients. GC rs4588 and rs2283679 SNPs were associated with increased risk of vitamin D(3) insufficiency and suboptimal increase in 25(OH)D(3) levels after D(3) supplementation. Individuals with these genotypes may require higher D(3) supplementation doses to achieve vitamin D(3) sufficiency.

Structuring survivorship care: discipline-specific clinician perspectives.

INTRODUCTION: Several models for survivorship care are prominent within the cancer literature; however, there is little empirical research that examines what oncology clinicians perceive to be the best approach to caring for cancer survivors, what services survivorship programs should include, and how prepared they feel to care for cancer survivors. METHODS: An IRB approved web-based survey of all clinical staff was conducted at a NCI designated comprehensive cancer center with a 49.8% response rate (N = 377). Data were summarized using frequencies and relative frequencies, and pairwise tests of statistical significance were utilized to evaluate differences between clinician type groups. RESULTS: Overall, the largest proportion of respondents preferred a disease-specific survivorship model (37.6%). This preference was specifically observed in oncology physicians and nurses. When asked where specific survivorship services should be provided, respondents indicated a preference for services directly related to survivors' medical treatment (i.e. information about late effects) to be delivered in a disease-specific survivorship clinic, and ancillary services (i.e. nutrition and fertility counseling) to be housed in a centralized comprehensive survivorship clinic. Physicians felt that they have significantly more information, training, and resources to care for cancer survivors than did oncology nurses. DISCUSSION/CONCLUSION: These results indicate that oncology clinicians prefer a combination of survivorship care delivery models where continuing medical needs are met in disease-specific clinics, and comprehensive wellness services are offered in a centralized comprehensive survivorship clinic. Results also suggest that planning for survivorship initiatives should include additional resources, education, and training for clinical staff. IMPLICATIONS FOR CANCER SURVIVORS: These findings underscore the need for a universally accepted definition of cancer survivorship, and support a model for delivering care to cancer survivors that is a blend of the disease-specific and comprehensive survivorship programs.
