Monthly palliative pelvic radiotherapy in advanced carcinoma of uterine cervix

Background: Patients with locally advanced cervical cancer are often severely distressed with incessant vaginal bleeding, offensive discharge and pelvic pain and are in some instances are beyond curative potential. At our institution we routinely use monthly palliative pelvic radiotherapy for these patients. Methods and Material: One hundred patients treated between 2000 & 2004 were included in this analysis. Patients were treated with parallel-opposed pelvic portals with megavoltage radiation monthly up to a maximum of three fractions (10Gy/ fraction). Patients with good response after second fraction were considered for intracavitary brachytherapy delivering 30Gy to point A. Response was documented with regard to relief of bleeding, vaginal discharge and pelvic pain. The other aspects evaluated were patient compliance, disease response, toxicity and survival. Results: Sixty-eight percent had FIGO stage IIIB, 12% had stage IVA and 14% had IVB disease. Twenty patients had metastatic disease. The median symptom duration was 5 months. Majority (67%) presented with vaginal bleeding, followed by discharge (69%) and pelvic pain (48%). All patients received at least one fraction of palliative pelvic radiotherapy. Sixty-one patients received the second fraction and 33 the third. Five patients received an intracavitary application. The overall response rates in terms of control of bleeding, discharge and pain were 100%, 49% and 33% respectively. The treatment was generally well tolerated with a median survival of 7 months. Conclusions: Monthly palliative pelvic radiotherapy results in satisfactory control of symptoms in patients with locally advanced carcinoma of cervix with acceptable complications

Empiric Radiotherapy for Lung Cancer Collaborative Group multi-institutional evidence-based guidelines for the use of empiric stereotactic body radiation therapy for non-small cell lung cancer without pathologic confirmation

The standard of care for managing early stage non-small cell lung cancer (NSCLC) is definitive surgical resection. Stereotactic body radiation therapy (SBRT) has become the standard treatment for patient who are medically inoperable, and it is increasingly being considered as an option in operable patients. With the growing use of screening thoracic CT scans for patients with a history of heavy smoking, as well as improved imaging capabilities, the discovery of small lung nodes has become a common dilemma. As a result, clinicians are increasingly faced with managing lung nodules in patients in whom diagnostic biopsy is not safe or feasible. Herein, we describe the scope of the problem, tools available for predicting the probability that a lung nodule is a malignancy, staging procedures, benefits of pathology-proven and empiric SBRT, considerations of safety based on location of the lesion of concern, and overall efficacy of SBRT

Epidemiology, diagnosis, and optimal management of glioma in adolescents and young adults

Neoplasms of the central nervous system (CNS) are the most frequently encountered solid tumors of childhood, but are less common in adolescents and young adults (AYA), aged 15–39 years. Gliomas account for 29%–35% of the CNS tumors in AYA, with approximately two-thirds being low-grade glioma (LGG) and the remaining being high-grade glioma (HGG). We review the epidemiology, work-up, and management of LGG and HGG, focusing on the particular issues faced by the AYA population relative to pediatric and adult populations. Visual pathway glioma and brainstem glioma, which represent unique clinical entities, are only briefly discussed. As a general management approach for both LGG and HGG, maximal safe resection should be attempted. AYA with LGG who undergo gross total resection (GTR) may be safely observed. As age increases and the risk factors for recurrence accumulate, adjuvant therapy should be more strongly considered with a strong consideration of advanced radiation techniques such as proton beam therapy to reduce long-term radiation-related toxicity. Recent results also suggest survival advantage for adult patients with the use of adjuvant chemotherapy when radiation is indicated. Whenever possible, AYA patients with HGG should be enrolled in a clinical trial for the benefit of centralized genetic and molecular prognostic review and best clinical care. Chemoradiation should be offered to all World Health Organization grade IV patients with concurrent and adjuvant chemotherapy after maximal safe resection. Younger adolescents with GTR of grade III lesions may consider radiotherapy alone or sequential radiotherapy and chemotherapy if unable to tolerate concurrent treatment. A more comprehensive classification of gliomas integrating pathology and molecular data is emerging, and this integrative strategy offers the potential to be more accurate and reproducible in guiding diagnostic, prognostic, and management decisions

Isolated non-Hodgkin's lymphoma of the pancreas: Case report and review of literature

Background: Isolated primary pancreatic lymphoma (PPL) is a rare extra-lymphatic non-Hodgkin\u2032s lymphoma comprising less than 1% of all extra-lymphatic lymphomas. It is seen in people of advanced age and there is a slight male preponderance. It is difficult to diagnose; the vague presenting symptoms and nonspecific laboratory/radiological findings make it difficult to differentiate the condition from pancreatic adenocarcinoma. Histopathological examination is of paramount importance to conclusively establish the diagnosis since the treatment involves lymphoma protocols, and prognosis and survival in PPL are considerably superior to that in adenocarcinoma pancreas. Case Report: We report a case of isolated PPL diagnosed after Tru-Cut biopsy and immunohistochemistry after a thorough staging workup. Result: The patient was treated with multi-agent combination chemotherapy followed by radiotherapy. Discussion: A review of literature was done using a Medline search to determine the incidence and prevalence of isolated PPL and to note the diagnosis and management of previously reported cases. Conclusion: An exceedingly rare entity, isolated PPLs need to be differentiated from pancreatic adenocarcinomas by histopathological evaluation since management is on the lines of other extralymphatic lymphomas and prognosis is significantly better

How Histopathologic Tumor Extent and Patterns of Recurrence Data Inform the Development of Radiation Therapy Treatment Volumes in Solid Malignancies

The ability to deliver highly conformal radiation therapy using intensity-modulated radiation therapy and particle therapy provides for new opportunities to improve patient outcomes by reducing treatment-related morbidities following radiation therapy. By reducing the volume of normal tissue exposed to radiation therapy (RD, while also allowing for the opportunity to escalate the dose of RT delivered to the tumor, use of conformal RT delivery should also provide the possibility of expanding the therapeutic index of radiotherapy. However, the ability to safely and confidently deliver conformal RT is largely dependent on our ability to clearly define the clinical target volume for radiation therapy, which requires an in-depth knowledge of histopathologic extent of different tumor types, as well as patterns of recurrence data. In this article, we provide a comprehensive review of the histopathologic and radiographic data that provide the basis for evidence-based guidelines for clinical tumor volume delineation.
