We describe a rare case of metastatic prostate cancer to bone marrow and synchronous multiple myeloma as the second malignant disease. Various diagnostic procedures, including cytomorphology and immunohistochemistry analyses together contributed to the detection of metastasis of prostate cancer and synchronous plasma cell proliferation in the bone marrow. The association between these two disorders is poorly understood however, some studies show that bone marrow microenvironment may play a crucial role. The need for further research in this regard is required to unfold this fascinating association.

For definitive treatment of carcinoma cervix with conformal radiation techniques, accurate target delineation is vitally important, yet a consensus definition of clinical target volume (CTV) remains variable within the literature. The aim of the present article is to review the guidelines for CTV delineation published in the literature and to present the guidelines practiced at our institute. For this a literature pub med/medline search was performed from January 2000 to December 2012 and reviewed to identify published articles on guidelines for CTV primary and pelvic lymph node (LN) delineation for carcinoma cervix. Taking into consideration the traditional bony landmark based fields for treating cancer cervix, the knowledge of the patterns of disease spread and recurrence and the findings from imaging studies identifying typical anatomic distributions of areas at risk of harbouring subclinical disease, the differences in various guidelines have been analyzed and discussed. The CTV in cervical cancer consists of the CTV nodal and CTV primary. In all the published guidelines, CTV nodal consists of common iliac, external iliac, internal iliac, pre-sacral and obturator group of lymph nodes, and CTV primary consists of the gross tumor volume, uterine cervix, uterine corpus, parametrium, upper third of vagina and uterosacral ligaments. The various guidelines differ however, in the definition for these individual component structures. This is the first report to provide the complete set of guidelines for delineating both the CTV primary and CTV nodal in combination.

Diminished vision due to choroidal metastasis as the primary symptom of lung cancer is very uncommon. Here, we report such a presentation in a 54-year-old male patient of small cell lung cancer. The outcome is usually dismal with this kind of presentation. The patient received systemic chemotherapy as well as intravitreal bevacizumab but with no improvement in vision. The patient had been given external beam radiotherapy and showed subjective improvement in his ocular symptoms.

Primary adenoid cystic carcinoma of lung is an unusual thoracic neoplasm, which is considered as a slow-growing low-grade malignancy. The primary treatment for this tumor is surgery. The role of radiotherapy, chemotherapy, and targeted agents is less well defined. Here we report a case of inoperable adenoid cystic carcinoma of the lung in a 42-year-old male, presenting with an unusual aggressive behavior. The patient received radiotherapy and oral tyrosine kinase inhibitor imatinib with effective palliation.

AIM To analyze overall and progression-free survival after letrozole in postmenopausal women with advanced breast cancer who failed after tamoxifen therapy. MATERIALS AND METHODS This is a retrospective analysis of 95 patients with breast cancer who were postmenopausal and had failed after tamoxifen therapy. Dose of letrozole was 2.5 mg daily until disease progressed. Patients had estrogen receptor- and/or progesterone receptor-positive tumors or both receptors were unknown. One complete course of (6 cycles) chemotherapy for metastatic disease was allowed. The primary end point was time to progression (TTP). Secondary end points included overall objective response rate (ORR), its duration, time to treatment failure (TTF), overall survival and tolerability. RESULTS Median TTP was 10 months. ORR was 21% with complete response rate of 9%. Nine patients died of disease during treatment. Median overall survival was 36 months. Median time to response was three months and median duration of response was 13 months. Time to chemotherapy was 13.5 months and TTF was 9.3 months. Treatment failure was seen in 76% of patients. Disease progression was the main cause for treatment failure. Treatment was well-tolerated by all patients. CONCLUSION This retrospective analysis shows that letrozole is quite effective as second line therapy in postmenopausal patients with advanced breast cancer who had failed after tamoxifen therapy.

PURPOSE Concurrent chemoradiation is the current standard of care in locally advanced head and neck cancer. But, in our setup, many patients of carcinoma larynx are treated with only radical radiotherapy because of poor general condition of the patients. This study was performed to assess the influence radical radiotherapy alone on functional preservation of larynx. MATERIALS AND METHODS 110 previously untreated patients with invasive squamous cell carcinoma of larynx were treated with radical radiotherapy alone between January 2006 and June 2009. Conventional one daily fraction of 2 Gy with total doses of 60-66 Gy was used. Voice preservation and local control at median follow-up period of 2 years were analyzed. Several host, tumor, and treatment parameters were also analyzed. RESULTS Among 110 patients, preservation of larynx was possible in 78 patients (71%). With radical radiotherapy alone, excellent preservation of larynx was achieved in stage I (88.9%) and stage II (75%) disease, while in advanced stages, results were not so encouraging. In stage III and stage IVA, larynx preservation was only 72.4% and 65.3%, respectively. Patients without any cartilage invasion had significantly better laryngeal preservation rate as compared to patients with cartilage invasion. (78.9% vs. 35.3%; P = 0.008). CONCLUSION Though concurrent chemoradiation is the standard of care in preservation of voice in laryngeal cancer, definitive radiotherapy alone may also be a good option in terms of preservation of larynx in patients of laryngeal cancer in community practice in the developing world where most of the patients cannot tolerate concurrent chemoradiation.

BACKGROUND Although conventional four- field radiotherapy based on bony landmarks has been traditionally used, areas of geographical miss due to individual variation in pelvic anatomy have been identified with advanced imaging techniques. AIMS The primary aim of this study is to evaluate the geographical miss in patientswhen using the conventional four-field planningplanning and to find out the impact of 3-D conformal CT based in patients with locally advanced carcinoma cervix. MATERIALS AND METHODS In 50 patients, target volume delineation was done on planning computed tomography (CT) scans, according to guidelines by Taylor et al. Patients were treated with modified four field plan, except for the superior, where field border was kept at L4-L5 interspace A dosimetric comparison was done between the conventional four-field based on bony landmarks and the target volume delineated on computed tomography. The disease free survival, pelvic and para aortic nodal free survival, distant failures free survival were calculated using Kaplan Meir Product Limit Method. RESULTS Patients were followed-up for a median period of 11 months. The median V95 for conventional and modified extended four field plans were 89.4% and 91.3% respectively. Patients with V95 for modified extended pelvic fields less than 91.3% had a trend toward inferior disease free survival (mean DFS 9.8 vs. 13.9 months) though the difference was not statistically significant log rank test. CONCLUSIONS Our preliminary data shows trend toward lower DFS in patients with inadequate target volume coverage. We recommend routine use of CT based planning for four field technique.
