Radiotherapy plays an important role in the treatment of localized primary malignancies involving the chest wall or intrathoracic malignancies. Secondary effects of radiotherapy on the lung result in radiation-induced lung disease. The phases of lung injury from radiation range from acute pneumonitis to chronic pulmonary fibrosis. Radiation pneumonitis is a clinical diagnosis based on the history of radiation, imaging findings, and the presence of classic symptoms after exclusion of infection, pulmonary embolism, heart failure, drug-induced pneumonitis, and progression of the primary tumor. Computed tomography (CT) is the preferred imaging modality as it provides a better picture of parenchymal changes. Lung biopsy is rarely required for the diagnosis. Treatment is necessary only for symptomatic patients. Mild symptoms can be treated with inhaled steroids while subacute to moderate symptoms with impaired lung function require oral corticosteroids. Patients who do not tolerate or are refractory to steroids can be considered for treatment with immunosuppressive agents such as azathioprine and cyclosporine. Improvements in radiation technique, as well as early diagnosis and appropriate treatment with high-dose steroids, will lead to lower rates of pneumonitis and an overall good prognosis.

Purpose Development of cancer chemotherapy treatment-induced hyperglycemia/ diabetes (secondary diabetes) is a major problem and has never been reported from India. The present study was planned to ascertain this in women undergoing curative chemotherapy for their breast cancer. Materials and Methods This was a retrospective chart-based study and was conducted in a cancer specialty hospital. The information on women who were nondiabetic at the start of the treatment was collected from the files. Details on cancer diagnosis, domicile, body mass index (BMI), type of diet, marital status, number of children, and previous history of diabetes if any were considered. The blood glucose levels before surgery and after the completion of radiotherapy were considered. World Health Organization (WHO) guidelines for diabetes were considered. The data were subjected to frequency and percentage and analyzed using Chi-square test. Association between the demographic details and development of Hyperglycemia or secondary diabetes or prediabetes was done using the Pearson’s correlation analysis. p < 0.05 was considered as statistically significant. Results A total of 474 cases were included in accordance with the inclusion criteria. The results indicated that by the end of the radiation treatment, 24.89% were prediabetic, 10.97% were diabetic after being in prediabetic stage, 8.22% became diabetic without going through a prediabetic stage, and that 55.91% did not develop either prediabetic or diabetic condition. Analysis of development of secondary diabetes and prediabetes with BMI (p < 0.0001) and age (p < 0.024) showed a strong correlation and was significant. Conclusion To the best of the authors’ knowledge, this is the first study from India, and the results indicate that the development of secondary diabetes in women undergoing curative chemotherapy is high. Attempts are underway to ascertain the cause for the development and how it can be mitigated.

Introduction The mainstay of management for locally advanced rectal cancer is chemoradiotherapy followed by surgical resection. Following chemoradiotherapy, a complete response may be detected clinically and radiologically (cCR) prior to surgery or pathologically after surgery (pCR). We aim to report the overall complete pathological response (pCR) rate and the reliability of detecting a cCR by conventional pre‐operative imaging. Methods A pre‐planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients treated by elective rectal resection were included. A pCR was defined as a ypT0 N0 EMVI negative primary tumour; a partial response represented any regression from baseline staging following chemoradiotherapy. The primary endpoint was the pCR rate. The secondary endpoint was agreement between post‐treatment MRI restaging (yMRI) and final pathological staging. Results Of 2572 patients undergoing rectal cancer surgery in 277 participating centres across 44 countries, 673 (26.2%) underwent chemoradiotherapy and surgery. The pCR rate was 10.3% (67/649), with a partial response in 35.9% (233/649) patients. Comparison of AJCC stage determined by post‐treatment yMRI with final pathology showed understaging in 13% (55/429) and overstaging in 34% (148/429). Agreement between yMRI and final pathology for T‐stage, N‐stage, or AJCC status were each graded as ‘fair’ only (n = 429, Kappa 0.25, 0.26 and 0.35 respectively). Conclusion The reported pCR rate of 10% highlights the potential for non‐operative management in selected cases. The limited strength of agreement between basic conventional post‐chemoradiotherapy imaging assessment techniques and pathology suggest alternative markers of response should be considered, in the context of controlled clinical trials.

Temporary central venous hemodialysis (HD) catheters are commonly used in end-stage renal disease (ESRD) patients while awaiting peritoneal dialysis catheter, arterio-venous fistula or graft placement and maturation. Catheter-related right atrial thrombus (CRAT) is a common finding in patients with central venous catheters (CVCs) and can cause CVC to malfunction. The incidence of CRAT is about 29% with a mortality of 18.3% or greater if not identified and managed appropriately. Two major types of right atrial (RA) thrombi have been identified. Type A thrombus usually originates in the peripheral veins embolizing to the RA. Type B originates within a structurally abnormal RA and is usually attached to the chamber walls or foreign bodies like CVC or intra-cardiac wires. There is a high risk of thrombi embolization leading to pulmonary embolism as in our patient, systemic embolization if a right to left shunt is present and potential hemodynamic compromise. The optimal therapeutic approach is still a subject of discussion, but timely catheter removal with prompt initiation of systemic anticoagulation is key. Surgical management is pursued when medical therapy fails or if the thrombus is greater than 6 cm. Our case is that of a 30-year-old male with CRAT successfully treated with surgical embolectomy after the failure of systemic anticoagulation. This case highlights the importance of early detection of CRAT, initiation of optimal medical therapy and the need for surgical intervention when medical therapy fails.
