Purpose: ABVD (doxorubicin, bleomycin,vinblastine, and dacarbazine) is not a standard regimen in children due to concerns regarding late effects. However, no studies have evaluated long-term toxicities of ABVD in children.

Methods: Total 154 pediatric Hodgkin lymphoma (HL) survivors uniformly treated with ABVD were clinically followed up as per institutional protocol.

Purpose: It is projected that approximately 50,000 new cases of prostate cancer will be diagnosed in 2020 in India. Survival has improved because of the development of effective drugs such as abiraterone acetate, but universal accessibility to treatment is not always possible because of cost constraints in lower- and middle-income countries. Recently, the National Comprehensive Cancer Network (NCCN) has included low-dose abiraterone (250 mg/day) with food as an alternative treatment option to full-dose abiraterone (1,000 mg/day) fasting.

Elevated serum interleukin-6 (IL-6) in Hodgkin lymphoma (HL) is reported to correlate with B symptoms, response rate and survival in adult patients. The authors studied prognostic significance of IL-6 expression by immunohistochemistry on Hodgkin-Reed Sternberg cells and background reactive cells in a retrospective cohort of pediatric HL patients treated with doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) from January 2009 through December 2013. Of 142 patients, tissue blocks were retrieved in 110 patients.

Clinical stage alone is used for risk stratification in treatment of pediatric advanced Hodgkin lymphoma (HL). To identify other risk factors, we collected data from three tertiary centers on 186 patients with advanced stage (IIB-IV) consecutively treated with Adriamycin, bleomycin, vinblastine, Dacarbazine (ABVD) chemotherapy ± radiotherapy. Freedom from treatment failure (FFTF) and overall survival (OS) were end points.

Data about the significance of F-FDG PET at interim assessment and end of treatment in pediatric Hodgkin lymphoma (HL) are limited. Patients (≤18 y) with HL were prospectively evaluated with contrast-enhanced CT (CECT) and PET combined with low-dose CT (PET/CT) at baseline, after 2 cycles of chemotherapy, and after completion of treatment. Revised International Working Group (RIW) criteria and Deauville 5 point-scale for response assessment by PET/CT were used.

Drug induced pulmonary toxicity is not uncommon with the use of various chemotherapeutic agents. Cyclophosphamide is a widely used chemotherapeutic drug in the treatment of breast cancer. Although rare, lung toxicity has been reported with cyclophosphamide use.

Primary prostatic lymphomas are extremely unusual neoplasms. Their rarity and nonspecific symptomatology at presentation usually prompt a clinical diagnosis of benign prostatic hyperplasia or chronic prostatitis, leading to significant delay in diagnosis. Clinical examination, serum prostate-specific antigen levels, and transrectal ultrasonography (TRUS) are not of much utility in differential diagnosis, and histological examination is the gold standard.
