Aims and objectives: This study aims to study the effect of geometric- and patient-related variables in achieving the desired dose-volume constraints to parotid for patients undergoing definitive/adjuvant intensity-modulated radiotherapy (IMRT) for head and neck squamous cell carcinomas (HNSCC). Subjects and methods: This retrospective study con...

Aim: The aim of this study was to report the patterns of recurrence, locoregional control, and survival of patients diagnosed with endometrial adenocarcinomas over a 7-year period after reclassifying them under the recent ESMO-ESGO-ESTRO (European Society of Medical Oncology/European Society of Gynaecological Oncology/European Society for Radiothe...

Objectives: To document the dose received by brachial plexus (BP) in patients treated with intensity-modulated radiotherapy (IMRT) for head-and-neck squamous cell carcinoma (HNSCC) and report the incidence of brachial plexopathy. Methods: Newly diagnosed patients of HNSCC treated with radical or adjuvant IMRT were included in this retrospective stu...

Background & objectives Oral mucositis is inflammation of mucosa of oral cavity which is an inevitable and acute side effect in patients undergoing chemoradiotherapy for head & neck cancer. Though many agents have been tried in prevention & treatment of oral mucositis, until date no single agent exists that is universally established to be effectiv...

Upper tracheal malignancies are rare, and long-term survival is even rarer, especially among the unresectable malignancies. A 66-year-old chronic smoker was diagnosed as a locally advanced, non-metastatic squamous cell carcinoma of the upper trachea. Being unresectable, he was treated with six cycles of concurrent weekly cisplatin and three-dimensi...

We report a case of a patient in his early 30s’ who presented with an ulcero-proliferative growth over the left buccal mucosa , he was also on treatment for CML in blast crisis on Hydroxyurea and a known case of Ichthyosis Follicularis, Alopecia, and Photophobia (IFAP) syndrome. Though a working diagnosis of chloroma / Hydroxyurea induced erosive L...

Spinal cord compression (SCC) is an unusual sequale of extra-medullary hematopoiesis (EMH). We report a patient diagnosed with β-thalassemia intermedia at the age of 7 years presenting as a 24-year-old with symptoms suggestive of paraparesis. MR imaging revealed long masses of EMH opposite T5-T11 and L5-S2 vertebrae with cord compression at T6 vert...

Adjuvant treatment options for Stage I seminoma include active surveillance, chemotherapy, and radiotherapy. Active surveillance may not be ideal for the average Indian patient. Of the two accepted adjuvant therapy options, namely single-dose carboplatin chemotherapy and radiotherapy to the retroperitoneal nodes, though it intuitively appears more...

Introduction: Hypofractionated External Beam Radiotherapy (HFRT) is a relatively new adjuvant Radiotherapy (RT) schedule for breast cancers following breast conservation surgery and less commonly, following mastectomy. Here we report our experience on normal tissue exposure and acute toxicity of HFRT after mastectomy. Aim: To assess the dosimetr...

Background: Brain metastasis from primary head and neck squamous cell carcinoma (HNSCC) is infrequent and probably under-reported thereby leading to paucity of information. Methods: Archives of two institutes in India were studied from 2005 to 2013 and relevant information regarding patient demographics, treatment details, and follow-up was obta...

We report a case of a patient aged 65 years' who presented with histopathological proven metastatic squamous cell cancer of the anal canal. After the necessary workup she was planned for Cisplatin and Fluoropyrimidine based palliative chemotherapy. On day 4 following chemotherapy the patient developed an episode of Generalized Tonic Clonic Seizures...

Background: Grade ≥2 acute xerostomia between 3D conformal radiotherapy (RT) and intensity-modulated radiotherapy (IMRT) was evaluated in patients with head and neck squamous cell carcinomas (HNSCCs) treated radically. Methods: Between 2005 and 2007, 59 patients with HNSCC (T1-3, N0-2b) were randomized to IMRT or 3D-RT. On RT, weekly xerostomia,...

A 60-year-old male, chronic alcoholic and smoker with decompensated cirrhosis was diagnosed with adenocarcinoma lower-third esophagus with multiple liver metastasis. While on palliative chemotherapy, the patient presented with a lesion at the tip of the nose. Excision of the lesion was performed suspecting mucormycosis. Histopathological examinatio...

Multiple primary malignancies (MPMs) are a known phenomenon. We present a rare case of multicentric carcinoma of left breast synchronous with carcinoma of right lung. There was a diagnostic dilemma about the nature of the lung lesion, which otherwise would have been labeled as a metastasis from the breast primary; however, the immunohistochemistry...
