ABSTRACT

We are reporting a case of pneumonia associated with pleural effusion during the neutropenic phase of induction chemotherapy. In spite of being Adenosine deaminase negative, the pleural effusion responded only to empiric therapy with antitubercular agents. The diagnosis was confirmed with positive PCR testing for mycobacterium tuberculosis.

ABSTRACT

AIM: To study the use of RapidArc techniques in the treatment of prostate cancer patients with hip prosthesis. BACKGROUND: An important aspect of treatment planning is to achieve dose homogeneity inside the planning target volume (PTV). Especially for those patients presenting with hip prosthesis, it becomes a challenging task to achieve dose uniformity inside the PTV. MATERIALS AND METHODS: Five prostate patients presenting with hip prosthesis who had undergone radical radiotherapy were selected for this study. Depending on the composition of prosthesis, a predefined set of Hounsfield values were assigned to each study set. RapidArc plans were generated on an Eclipse treatment planning system. Two arcs that include clockwise and counter-clockwise arcs were used in all these cases. To avoid beams passing through the prosthesis, a simple structure was defined around it with 1 cm margin and a strict dose constraint applied to the block during VMAT optimization. RESULTS: The mean D2/D98 ratio of PTV for all the patients was 1.06 ± 0.01. The mean percentage rectum volume receiving 50 Gy, 60 Gy, 70 Gy and 75 Gy for all the patients were 33.1 ± 5.9, 21.7 ± 5.5, 13.8 ± 4.4 and 9.5 ± 3.0, respectively. CONCLUSIONS: This study shows that using a double arc RapidArc technique is a simple and effective treatment method of treating prostate cancer in patients presenting with a hip prosthesis. The definition of a beam avoidance structure encompassing the prosthesis and applying strict dose constraints to it reduces the beam contribution to the prosthesis.

ABSTRACT

OBJECTIVE: The use of non-platinum drugs in concurrent chemoradiation in carcinoma cervix has not been well explored and hence a two arm study was planned to compare the outcome of concomitant cisplatin or gemcitabine in locally advanced carcinoma cervix. METHODS: Thirty six patients were evaluated in this study for response rates and complications. These patients were divided into two arms, sixteen patients in the cisplatin arm and twenty patients in the gemcitabine arm. Cisplatin and gemcitabine were given as i.v. infusion at doses of 40 mg/m(2) and 150 mg/m(2) respectively for five weeks concomitant with radiotherapy. All patients had received pelvic radiotherapy to a dose of 50 Gy/25 fraction/5 weeks by four field box technique followed by high-dose-rate brachytherapy (3 sessions, each of 7.5 Gy to point A). RESULTS: Median follow up was of 10.4 months (range, 3 to 36 months) and 10.9 months (range, 2 to 49 months) in the cisplatin and gemcitabine arms, respectively. At first follow up, 68.8% in the cisplatin arm and 70% in the gemcitabine arm had achieved complete response (p=0.93). Similar response rates were noted in different stages in both arms. None of the patients except one developed grade 4 toxicity. Similar toxicity profiles were observed in both arms. Local disease control, distant disease free survival and overall survival was 68.8% vs. 70%, 93.8% vs. 85%, 68.8% vs. 60% in the cisplatin and gemcitabine arms, respectively. CONCLUSION: Weekly gemcitabine had similar disease control and tolerable toxicity profile with cisplatin. Gemcitabine may be used as an alternative to cisplatin in patients with compromised renal function.

ABSTRACT

Brain metastases constitute one of the most common distant metastases of cancer and are increasingly being detected with better diagnostic tools. The standard of care for solitary brain metastases with the primary disease under control is surgery followed by radiotherapy. Radiotherapy is also the primary modality for the treatment of multiple brain metastases, and improves both the quality of life and survival of patient. Unfortunately, more than half of these treated patients eventually progress leading to a therapeutic dilemma. Another course of radiotherapy is a viable but underutilized option. Reirradiation resolves distressing symptoms and has shown to improve survival with minimal late neurotoxicity. Reirradiation has conventionally been done with whole brain radiotherapy, but now studies with stereotactic radiosurgery have also shown promising results. In this review, we focus on reirradiation as a treatment modality in such patients. We performed a literature search in MEDLINE (www.pubmed.org) with key words brain metastases, reirradiation, whole brain radiotherapy, stereotactic radiosurgery, interstial brachytherapy, and brain. The search was limited to the English literature and human subjects.

ABSTRACT

Cylindric cell carcinomas (transitional cell carcinomas) are a rare and distinct histopathological entity presenting in the head and neck region. They have been known by myriads of nomenclature like cylindric carcinomas, nonkeratinizing sinonasal carcinoma, papillary carcinoma, cylindrical or columnar cell carcinoma, intermediate cell carcinoma, Schneiderian carcinoma, and Ringertz carcinoma. They are considered a variant of nonkeratinizing squamous cell carcinoma. Cylindric carcinomas are usually described in the sinus and nasal cavity and rarely said to involve nasopharynx and larynx. Only passing references have been made for its presentation in oropharynx including tonsils and the base of the tongue. We report here a rare case of transitional cell carcinoma presenting in the base of the tongue. There are no separate treatment recommendations in the literature, and the management is on the lines of treatment of squamous cell carcinoma. We report here a case of cylindric cell carcinoma presenting in the base of the tongue. The patient was staged as having cT2 N3 M0 (Stage IV B) disease. The patient received palliative radiotherapy of 20 Gy in five fractions followed by chemotherapy with injection paclitaxel and carboplatin. A partial response to treatment was achieved at the time of writing this report.

ABSTRACT

Primary rhabdoid tumor of lung is a rare histological and clinical entity. Lung tumors with rhabdoid features have been included as variants of large-cell carcinoma in the 1999 World Health Organization (WHO) classification of lung tumors. A large-cell carcinoma with a rhabdoid phenotype (LCCRP) is unusual, with only 38 cases reported till date. We report the clinical details of one such case that was treated with pneumonectomy and adjuvant chemotherapy. We also present a review of the literature. To identify relevant articles, we searched PubMed, Ovid, and IngentaConnect databases using the key words 'rhabdoid,' 'lung cancer,' and 'primary rhabdoid tumor of lung.'

ABSTRACT

INTRODUCTION: Discussion of bad news and resuscitation in terminal cancer is an important but difficult and often neglected issue in day-to-day oncology practice. MATERIALS AND METHODS: We interviewed 35 radiation oncologists using an indigenous 15-item questionnaire on their beliefs about breaking bad news and resuscitation to terminal cancer patients. RESULTS: Most responders had an oncology experience of three to seven years (20/35). Thirty-two were comfortable discussing cancer diagnosis, prognosis and life expectancy-related issues. A similar number believed all cancer-related information should be disclosed, while only four believed in imparting all information in one visit. All agreed that disclosing sensitive information did not affect survival. When requested by relatives to withhold truth from patients, 11 said they would not comply, 22 agreed to tell the truth only if asked and two agreed to avoid difficult questions. Twenty responders denied having been adequately trained in breaking bad news and were keen on dedicated classes or sessions in this area of practice. Most (33/35) believed that Indian patients were keen on knowing their diagnosis and prognosis. Although all agreed to the importance of discussing resuscitation, only 17 believed patients should be involved. Majority (20/35) agreed that the issue needs to be discussed while the patient was conscious. Patients with unsalvageable disease were deemed unsuitable for aggressive resuscitation by 30 responders while the rest believed it should be offered to all. Most (21/35) admitted to feeling depressed after breaking bad news though only seven felt disclosure was more stressful than untruthful statements. Only four knew of a law regarding resuscitation in cancer. CONCLUSION: Observing the widely varied beliefs and practices for disclosing bad news, it is recommended that such training be a regular part of medicine curriculum, especially in the Oncology setting.

ABSTRACT

Sarcomatoid carcinomas are rare tumors. These tumors have been reported at other sites, but head and neck origin is extremely uncommon. We report here a rare case of sarcomatoid carcinoma involving the maxilla. Only four such cases with maxillary origin have been discussed in English literature earlier. As compared to squamous cell carcinoma of maxilla, this variant is associated with poor prognosis and advanced disease at presentation, as was also seen in our case. There are no standard recommendations for management owing to the rarity of this histology. Surgery and radiotherapy form the mainstays of treatment. Exploration of the role of chemotherapy and novel targeted therapy agents is warranted in order to improve treatment results.
