Management of Metastatic Anal Cancer

Metastatic squamous cell carcinoma of the anal canal is a rare presentation that is suspected in patients with risk factors such as known primary anal cancer, human papillomavirus/human immunodeficiency virus, immunosuppression, smoking, and receptive anal intercourse. Patients may present with metastasis at the index presentation of anal cancer or metastases may occur following the chemoradiation of the primary tumor. Treatment is focused on systemic therapy with chemotherapy, with the consideration of immunotherapy as second-line therapy. Predictive biomarkers may be able to personalize treatment in the future. Clinical trials of different chemotherapy and immunotherapy combinations are active to improve current management.

Quality of End-of-Life Care in Gastrointestinal Cancers: A 13-Year Population-Based Retrospective Analysis in Ontario, Canada

Population-based quality indicators of either aggressive or supportive care at end of life (EOL), especially when specific to a cancer type, help to inform quality improvement efforts. This is a population-based, retrospective cohort study of gastrointestinal (GI) cancer decedents in Ontario from 1 January 2006-31 December 2018, using administrative data. Quality indices included hospitalizations, emergency department (ED) use, intensive care unit admissions, receipt of chemotherapy, physician house call, and palliative home care in the last 14-30 days of life. Previously defined aggregate measures of both aggressive and supportive care at end of life were also used. In our population of 69,983 patients who died of a GI malignancy during the study period, the odds of experiencing aggressive care at EOL remained stable, while the odds of experiencing supportive care at EOL increased. Most of our population received palliative care in the last year of life (n = 65,076, 93.0%) and a palliative care home care service in the last 30 days of life (n = 45,327, 70.0%). A significant number of patients also experienced death in an acute care hospital bed (n = 28,721, 41.0%) or had a new hospitalisation in the last 30 days of life (n = 33,283, 51.4%). The majority of patients received palliative care in the last year of life, and a majority received a palliative care home service within the last 30 days of life. The odds of receiving supportive care at EOL have increased over time. Differences in care exist according to income, age, and rurality.

Care Patterns and Overall Survival in Patients With Early-Onset Metastatic Colorectal Cancer

PURPOSE

Colorectal cancer (CRC) incidence in patients younger than 50 years of age, commonly defined as early-onset (EO-CRC), is rising. EO-CRC often presents with distinct clinicopathologic features. However, data on prognosis are conflicting and outcomes with modern treatment approaches for metastatic disease are still limited.

MATERIALS AND METHODS

We prospectively enrolled patients with metastatic CRC (mCRC) to a biobanking and clinical data collection protocol from 2014 to 2018. We grouped the cohort based on age at initial diagnosis: < 40 years, 40-49 years, and ≥ 50 years. We used regression models to examine associations among age at initial diagnosis, treatments, clinicopathologic features, and survival.

RESULTS

We identified 466 patients with mCRC (45 [10%] age < 40 years, 109 [23%] age 40-49 years, and 312 [67%] age ≥ 50 years). Patients < 40 years of age were more likely to have received multiple metastatic resections (odds ratio [OR], 3.533; P = .0066) than their older counterparts. Patients with EO-CRC were more likely to receive triplet therapy than patients > 50 years of age (age < 40 years: OR, 6.738; P = .0002; age 40-49 years: OR, 2.949; P = .0166). Patients 40-49 years of age were more likely to have received anti-EGFR therapy (OR, 2.633; P = .0016). Despite differences in care patterns, age did not predict overall survival.

CONCLUSION

Despite patients with EO-CRC receiving more intensive treatments, survival was similar to the older counterpart. However, EO-CRC had clinical and molecular features associated with worse prognoses. Improved biologic understanding is needed to optimize clinical management of EO-CRC. The cost-benefit ratio of exposing patients with EO-CRC to more intensive treatments has to be carefully evaluated.

Changes of End of Life Practices for Cancer Patients and Their Association with Hospice Palliative Care Referral over 2009-2014: A Single Institution Study

Purpose

In Korea, hospice palliative care (HPC) provision for cancer patients has increased recently. However, whether end of life (EoL) care practices have improved along with the development of HPC is unclear. We intended to investigate the changes in EoL care practices and their association with HPC referral.

Materials and Methods

Retrospective medical record review of adult cancer patients who died at National Cancer Center Korea from 1 January 2009 to 31 December 2014 was performed. Changes of EoL practices including chemotherapy within 2 weeks from death, death in intensive care unit (ICU), documentation of “do not resuscitate (DNR)” within 7 days from death and referral to HPC from 2009 to 2014 were analyzed as well as the association between referral to HPC and other practices.

Results

A total of 2,377 cases were included in the analysis. Between 2009 and 2014, referral to HPC increased and DNR documentation within 7 days from death decreased significantly. Cases for chemotherapy within 2 weeks from death and death in ICU didn’t change over the study period. Patients referred to HPC were less likely to receive chemotherapy within 2 weeks from death, die in ICU and document DNR within 7 days from death.

Conclusion

During the study period, EoL practices among cancer patients partly changed toward less aggressive in our institution. HPC referral was associated with less aggressive cancer care at the EoL. Policies to promote EoL discussion are necessary to improve the EoL practices of cancer patients.

Palliative care consultation and aggressive care at end of life in unresectable pancreatic cancer

Background

Palliative care (pc) consultation has been associated with less aggressive care at end of life in a number of malignancies, but the effect of the consultation timing has not yet been fully characterized. For patients with unresectable pancreatic cancer (upcc), aggressive and resource-intensive treatment at the end of life can be costly, but not necessarily of better quality. In the present study, we investigated the association, if any, between the timing of specialist pc consultation and indicators of aggressive care at end of life in patients with upcc.

Methods

This retrospective cohort study examined the potential effect of the timing of specialist pc consultation on key indicators of aggressive care at end of life in all patients diagnosed with upcc in Nova Scotia between 1 January 2010 and 31 December 2015. Statistical analysis included univariable and multivariable logistic regression.

Results

In the 365 patients identified for inclusion in the study, specialist pc consultation was found to be associated with decreased odds of experiencing an indicator of aggressive care at end of life; however, the timing of the consultation was not significant. Residency in an urban area was associated with decreased odds of experiencing an indicator of aggressive care at end of life. We observed no association between experiencing an indicator of aggressive care at end of life and consultation with medical oncology or radiation oncology.

Conclusions

Regardless of timing, specialist pc consultation was associated with decreased odds of experiencing an indicator of aggressive care at end of life. That finding provides further evidence to support the integral role of pc in managing patients with a life-limiting malignancy.
