The purpose of the present review was to provide evidence-based guidance about the provision of cytoreductive surgery (crs) with hyperthermic intraperitoneal chemotherapy (hipec) in the treatment of peritoneal cancers. ⋯ Recommendation 1a: For patients with newly diagnosed stage iii primary epithelial ovarian or fallopian tube carcinoma, or primary peritoneal carcinoma, hipec should be considered for those with at least stable disease after neoadjuvant chemotherapy at the time that interval crs (if complete) or optimal cytoreduction is achieved. Recommendation 1b: There is insufficient evidence to recommend the addition of hipec when primary crs is performed for patients with newly diagnosed advanced primary epithelial ovarian or fallopian tube carcinoma, or primary peritoneal carcinoma, outside of a clinical trial. Recommendation 2: There is insufficient evidence to recommend hipec with crs in patients with recurrent ovarian cancer outside the context of a clinical trial. Recommendation 3: There is insufficient evidence to recommend hipec with crs in patients with peritoneal colorectal carcinomatosis outside the context of a clinical trial. Recommendation 4: There is insufficient evidence to recommend hipec with crs for the prevention of peritoneal carcinomatosis in colorectal cancer outside the context of a clinical trial; however, hipec using oxaliplatin is not recommended. Recommendation 5: There is insufficient evidence to recommend hipec with crs for the treatment of gastric peritoneal carcinomatosis outside the context of a clinical trial. Recommendation 6: There is insufficient evidence to recommend hipec with crs for the prevention of gastric peritoneal carcinomatosis outside the context of a clinical trial. Recommendation 7: There is insufficient evidence to recommend hipec with crs as a standard of care in patients with malignant peritoneal mesothelioma; however, patients should be referred to hipec specialty centres for assessment for treatment as part of an ongoing research protocol. Recommendation 8: There is insufficient evidence to recommend hipec with crs as a standard of care in patients with disseminated mucinous neoplasm in the appendix; however, patients should be referred to hipec specialty centres for assessment for treatment as part of an ongoing research protocol.

To date, the role of adjuvant systemic therapy in stages ii and iii colon cancer remains a topic of interest and debate. The objective of the present review was to assess the most recent data, specifically addressing methods of risk stratification, duration of therapy, and future directions. ⋯ Locoregional disease, histopathology, age, laterality, and a number of other biologic and molecular markers appear to have a role in disease risk stratification. The duration of adjuvant therapy for stage iii disease can vary based on risk factors, but use of adjuvant therapy and duration of therapy in stage ii disease remain controversial. Future directions should include genomic assays and improved study design to provide concrete evidence about the duration of adjuvant folfox or capox and about other types of chemotherapy and immunotherapy.

Medullary thyroid carcinoma (mtc) is a rare malignancy of the thyroid gland, and raising awareness of the recommended diagnostic workup and pathologic characteristics of this malignancy is therefore important. ⋯ Although the initial diagnosis of a suspicious thyroid nodule is the same for differentiated thyroid carcinoma and mtc, the remainder of the workup and diagnosis for mtc is distinct.

Radiation oncology (ro) is one of several specialties identified by the Royal College of Physicians and Surgeons of Canada with employment difficulties for graduating trainees. The purpose of the present study was to determine the employment status and location of recent Canadian ro trainees within 2 years after graduation, to monitor workforce recruitment trends over time, and to capture the opinions of program directors about employment difficulty for graduates and resident morale. Visa trainee graduates were excluded. ⋯ Employment challenges for newly certified Canadian-trained radiation oncologists continue. However, compared with the situation 2 years ago, trends in the Canadian ro job market suggest a modest improvement, with more staff employment in Canada and lower emigration rates for jobs abroad.

Case Reports
Pembrolizumab-induced obstructive bronchiolitis in a patient with stage IV non-small-cell lung cancer.
Immune checkpoint inhibitors are now a standard of care for the management of many metastatic cancers, including non-small-cell lung cancer. Pembrolizumab, a selective anti-PD-1 monoclonal antibody, augments the host antitumoural response. This hyperactivation of the immune system has side effects, the so-called immune-related adverse effects. The objective of this case report was to review and point out a new pattern of immune checkpoint inhibitor-associated pneumonitis. ⋯ To our knowledge, this is the first description of a case of pembrolizumab-induced obstructive bronchiolitis. Various patterns of immune checkpoint inhibitor-associated lung disease have been described, and bronchiolitis should be included in the differential diagnosis.
