External beam radiation plus intraluminal brachytherapy in locally advanced, inoperable carcinoma esophagus: A retrospective study from tertiary cancer care center

Background: Worldwide, an estimated 572,034 esophageal cancer cases and 508,585 deaths occurred in 2018 and it accounts for approximately 3.2% of all malignancy. Because esophagus has no serosal covering with extensive, longitudinal connecting system of lymphatic plexus, direct invasion to contiguous structures and lymph node metastasis occurs early. Unresectable or metastatic disease at the time of diagnosis is seen in approximately 80% of patients, with cure rate <15% and thus making carcinoma of esophagus is one of the most dreaded malignancies. As most of the patients are diagnosed in locally advanced or metastatic stage, so curative surgical resection is not an option. Hence, in these groups of patients, other treatment modalities including concurrent chemoradiation have been tried. However, many of these patients are in a poor general condition so that radical concurrent chemoradiation as an alternative surgical resection could not be offered. In this group of patients, only radiotherapy (RT) is an option in intention to improve quality of life and to increase disease-free survival (DFS) if possible. As there is more chance local failure when patients treated with only external beam RT (EBRT), increasing dose to tumor may improve local control. Intraluminal brachytherapy (ILBT) is an important treatment option for dose escalation along with EBRT in the treatment of locally advanced and inoperable carcinoma esophagus. ILBT provides focal dose escalation, rapid reduction tumor, rapid restoration of swallowing function with sparing of surrounding normal tissue, and potentially improving therapeutic ratio. Hence, based on these facts, following EBRT, ILBT is an effective adjuvant modality to delivered high tumoricidal dose which can facilitate good local control, DFS with acceptable toxicity. We have used ILBT alone as palliative RT and combined modality with EBRT as radical treatment approach. Objectives: The aim of our study is to evaluate efficacy and safety of external beam radiation plus ILBT in locally advanced, inoperable carcinoma of esophagus in terms of improving local control, DFS, toxicity, and quality of life. Materials and Methods: A total of 58 carcinoma esophagus patients treated with EBRT plus ILBT in our RT department from 2012 to 2015 analyzed retrospectively. EBRT, total dose of 40 Gy/20 fractions, delivered in 4 weeks, using anteroposterior posteroanterior portal in cobalt-60 machine. Two–three weeks after completion of EBRT, ILBT was done using esophageal budgie. The total dose of brachytherapy was 10 Gy in two fractions, 1 week apart, 5 Gy in each fraction. EBRT and ILBT treatment completed in 8–9 weeks. Response assessed by clinical assessment, upper gastrointestinal endoscopy, and contrast-enhanced computed tomography chest and abdomen initially at 3 months and then at 6 months. Results: Local disease control seen in 65% of patients. With a median follow-up of 15 months, the median DFS was 8 months and median overall survival was 14 months. Regional nodal failure and distant metastasis were seen in 35% and 46% of patients, respectively. The incidence of acute mucositis was seen in 75% of patients and late toxicity is seen in 25% of cases. Swallowing function preserved in >87% of patients. Conclusion: In patients with locally advanced carcinoma of esophagus and poor performance status who are unable to tolerate radical concurrent chemoradiation, combination of EBRT plus ILBT produces good local control, DFS, and durable relief of dysphagia with acceptable toxicity.

Concurrent chemoradiation with paclitaxel in locally advanced head and neck cancer: A feasibility study from tertiary cancer care center

Background: In India, the majority of the head and neck squamous cell carcinoma (SCC) of head and neck (60–80%) presented in locally or locoregionally advanced stage but non-metastatic disease as compared to 40% in developed nations. Uncontrolled local and/or locoregional disease causes most fatalities and predominant failure pattern is local and/or locoregional. Concurrent chemoradiation (CRT) is now standard of care. However, regarding either the optimal scheduling of chemotherapy regimen or radiotherapy (RT) dose fractionation scheme, no consensus exists. Paclitaxel is also active agents against squamous cell carcinoma of head and neck. Weekly paclitaxel appeared to be equivalent to weekly cisplatin with concurrent radiation in the treatment of locally advanced SCC of head and neck cancer (HNC). Concurrent chemoradiotherapy with paclitaxel in locally advanced head and neck malignancy is recommended in NCCN Guideline. Objectives: The aim of our study is feasibility and efficacy of CRT with paclitaxel for the treatment locally advanced HNC in our institute, Nil Ratan Sircar Medical College and Hospital, Kolkata. Material and Methods: Between January 2014 and December 2018 ninety eight (98) previously untreated patients with locally advanced histologically confirmed carcinoma oral cavity, oropharynx, and hypopharynx treated with CRT. Chemotherapy consisted of paclitaxel at a dose 40 mg/m2 over 1 h given once weekly from 1st week of RT, up to 4–6 cycles. RT consisted of 66 Gy/33#/61/2 weeks, 2 Gy/fraction, delivered by two parallel opposed lateral face and neck and low anterior neck portal, in cobalt 60 machines. Toxicity was graded using Common Terminology Criteria for Adverse Events v3. To assess response to therapy contrast-enhanced computed tomography (CECT) head and neck and/or magnetic resonance imaging head and neck; CECT chest or whole-body fluorodeoxyglucose and positron emission tomography computed tomography scan were done. Results: Overall complete response (CR) rate seen in 68% and partial response seen in 32% patients. Two-year disease-free survival, progression free survival, and overall survival were 59%, 72% and 85%, respectively. Grade II acute skin reaction seen in 45% patients and Grade III acute skin reaction seen in 55% patients. Similarly, Grades II and III mucosal reaction is seen in 48% and 52% patients. All patients experience Grade II dysphagia and managed conservatively. Conclusions: CRT with paclitaxel in locally advanced HNC is safe and confers high CR rate with acceptable toxicity. However, more randomized study with large number of patients is needed to come to conclusions regarding its efficacy.

Epidemiology and prevalence of breast cancer: A retrospective study in a tertiary health care center in Kolkata over one decade

Background: Breast cancer is a major public health problem for women throughout the world. According to GLOBOCAN 2012, India along with the United States and China is responsible for almost one-third of global breast cancer burden. There has been 11.54% increase in incidence and 13.82% increase in mortality due to breast cancer in India from 2008 to 2012. According to GLOBOCAN 2018, for both sexes, breast cancer second most common cancer after lung cancer accounting for 11.6% of total cases. Most of the cases diagnosis at an advanced stage because of inadequate screening, lack of appropriate medical facilities thereby increasing breast cancer mortality. It is the second most common malignancy among Indian women accounting for 7% of global burden of breast cancer. Incidence of breast carcinoma varied in the different regions of the world with lowest incidence in Africa, Asia and highest incidence in North America and Europe. This geographic variability is not only to environmental factors but also to lifestyle. There is a paucity of epidemiological data regarding carcinoma of breast. Objectives: The aims of our study were to evaluate the prevalence and epidemiology of breast cancer in our institution, N.R.S. Medical College Kolkata. Materials and Methods: We have analyzed 4172 newly diagnosed breast carcinoma cases, registered at N.R.S. Medical College and Hospital, Kolkata, West Bengal, India, over one decade, in between January 2008 and December 2017 retrospectively. A total of 4172 cases confirmed by pathological examination were included for analysis. Demographic and clinicopathological profile and management offered to the breast cancer patients were recorded from the medical records file. The staging was performed using American Joint Committee on Cancer tumor, node, and metastasis classification staging system. Results: In our study, about 63% of the patients came from urban areas and 37% from rural areas. The mean age at diagnosis was 52 ± 9.5 years, with a range from 26 to 82 years. The age at menarche in this study ranged from 10 to 16 years, mean being 12 ± 1.5 years. Age at the time of first pregnancy ranged from 19 to 32 years, with the mean age being 22 ± 6.2 years. Family history of breast carcinoma in first and second degree relatives was found in 92 (2.2%) patients in this study. Approximately 5% (216) patients were nulliparous. About 63% of the patients were postmenopausal while 36% were premenopausal. Common presenting symptoms include breast lump (100%) and axillary swelling (33%). Histologically, 99.5% cases were infiltrating ductal carcinoma, and it was most common histology. Most patients were diagnosed with Grade II tumors (45%) followed by Grades I and III, and approximately 75% of the patients were in Stages II and III and 10% patients in Stage IV. The most common site of metastasis was lung (33%), bone (26%), liver (23%), and brain (14%). Conclusions: The majority of the breast carcinoma patients presented with Stages II and III disease, approximately 99% cases were infiltrating ductal carcinoma, not otherwise specified and were mainly Grade II followed by Grade III disease. The prevalence of estrogen receptor, progesterone receptor hormone receptor status and Her2/neu status in the population needs further investigation in the future. The government needs to urgently strengthen and augment the existing facilities including screening, which is inadequate at present to handle the current breast cancer load in India.

Palliative radiotherapy in locally advanced and metastatic carcinoma of lung with two radiotherapy regimens: A randomized comparative study from tertiary health-care cancer center

Background: Worldwide, leading cause of cancer mortality is lung cancer. Approximately 63,000/year new lung cancer cases reported in India. Around 80–85% of patients of lung cancer is non-small cell histology (non-small cell lung cancer) and over >90% of patients presented locally advanced and metastatic disease. Hence, in these patients, population curative treatment approach with radiotherapy (RT) and chemotherapy in most of the time is non-viable option yielding short survival and relatively poor prognosis. In majority of such cases, the only aim of treatment remains palliative, the main aim is to improve quality of life. Although there are other medical management of symptoms palliation, radiation therapy is the cheapest option, quite effective, time efficient, and well tolerated in providing relief from symptoms. The rate of palliation of symptoms is quite high for chest pain and hemoptysis at 60–80%, whereas cough and dyspnea are improved in only 50–70%. For intrathoracic disease with obstructive symptoms, 30 Gy/10# over 2 weeks are generally recommended. Patients with poor performance status, advanced age, and associated comorbidity at the time of diagnosis, for which daily RT over 2–3 weeks is logistically difficult, 1–2 fractions have been utilized with good results. There are multiple randomized trials showed that both short and long RT course were equally effective for symptoms control. Aims and Objectives: The aims of our study are to compare the outcome, symptom control and assess toxicity profile in locally advanced lung cancer patient with 17 Gy/2 fractions (8.5 Gy/fraction, × 2 fractions) only on Saturdays over 2 weeks versus 30 Gy/10 fractions (3 Gy/fraction) over 2 weeks and to compare quality of life. Materials and Methods: This study was a single-institutional, prospective, open-labeled, randomized controlled study. Eligible patients were age ≥18 years with histopathologically proven lung carcinoma which was inoperable Stage III or IV disease and too locally advanced to curative concurrent chemoradiation, pulmonary symptoms attributable to the primary tumor, Eastern Cooperative Oncology Group (ECOG) performance status ≤3, and adequate hematologic (hemoglobin >10 g/dl; absolute neutrophil count >1500; platelet count >100,000/ml; and hepatic and renal function calculated creatinine >60 ml/min). Patients with bleeding diathesis, emphysematous bullae, poor respiratory function or reserve, pregnancy, and ECOG performance status >3 were excluded from the study. Results: Age, stage, histopathology, and pre-treatment symptoms score between two groups were comparable and statistically not significant. Pain in chest due to lung cancer was decreased in both arms due to treatment (at treatment completion Arm A = 47.62 and Arm B = 38.09). However, at the 2nd follow-up, difference between two arms was statistically significant where Arm A = 27.78 and Arm B = 15.00; P = 0.005. Global health status of patients in this study was improved in both arms due to treatment. Physical functioning emotional functioning, role functioning, global health status, cognitive functioning, and social functioning were improved in both arms due to treatment and kept improving during follow-up, but difference between two arms was not significance. Conclusions: Although overall symptom palliation, toxicity profile, and quality of life parameters are almost equal in both arms, patients with short expected survival, 8.5 Gy × 2 fractions would be preferable, limiting the number of hospital visit to a minimum. On the other hand, 3 Gy × 10 fractions schedule can be chosen for those patients with longer expected survival and better ECOG status, due to prolong duration of palliative response.

Adjuvant chemotherapy with six cycles of AC regimen versus three cycles of AC regimen followed by three cycles of Paclitaxel in node-positive breast cancer.

Context: Antracycline-Cyclophosphamide (AC) along with Paclitaxel/Docetaxel, either in combination or sequential regimens, is showing superior results than Anthracycline-containing regimens. Aims: This study was designed to determine whether adding Paclitaxel to a standard adjuvant chemotherapy regimen AC for breast cancer patients would prolong the time to recurrence and survival. Settings and Design: Randomized, prospective, open-labeled, single-institutional study. Materials and Methods: Fifty stage II breast cancer patients accruing 25 patients in each arm, treated between July 2007 and January 2010, were included in the study. Initial surgical treatment was Modified Radical Mastectomy. Systemic therapy was to have begun within 4-6 weeks of the patient's surgery. In the control arm, all the patients were treated with six cycles of adjuvant chemotherapy with AC regimen repeated at an interval of 3 weeks. For the study arm, the patients received adjuvant chemotherapy with three cycles of AC regimen followed by three cycles of Paclitaxel, repeated at an interval of 3 weeks. All the patients of both the arms received locoregional external beam radiotherapy (EBRT) after the entire course of chemotherapy. All the hormone receptor-positive patients received Tamoxifen. Statistical Analysis Used: Statistical analysis was performed using the chi-square test and the Kaplan Meier survival analysis with the log-rank (Mantel-Cox) test. Results: Adding Paclitaxel to AC resulted in a statistically significant disease-free survival. The overall survival was also improved significantly. The toxicity profile in both the arms was comparable. Conclusions: In early and node-positive breast cancer, the addition of three cycles of Paclitaxel after completion of three cycles of AC improves the disease-free and overall survival.

External clues to inner malformations.

A malformation is a morphological defect of an organ, or a larger region of the body resulting from an intrinsically abnormal developmental process. In this analysis of 1421 neonatal autopsies performed between 1984 and 1993, 243 (17.1%) cases showed malformations. The data was analysed to find external cues to internal malformations. Twenty three (85%) of the 27 neonates with various facial abnormalities had associated internal malformations in the form of cardiac (n = 11; 40%), renal (n = 7; 25%), or gastrointestinal (n = 3; 11%) abnormalities and diaphragmatic hernia (n = 2). Sixty seven neonates had neural abnormalities. These were associated with cardiac (n = 7; 10%), renal (n = 12; 18%) or gastrointestinal (n = 7; 10%) abnormalities; 43 cases, however, did not have any associated malformations. Renal malformations (n = 66) had highest association with skeletal abnormalities (n = 9; 22%). As many as 45(76%) of the 59 cases with cardiac abnormalities had no external anomalies. Five cases of hypoplastic lungs were seen, all associated with external malformations.

Paraproteins and plasma cell dyscrasias.

Serum protein electrophoresis done on 1100 patients with various diseases in one year demonstrated M-band in 31 patients. Most (87%) had the classical features of plasma cell dyscrasia (PCD), however a few had unusual presentations which are highlighted. A 22-year-old male operated for a massive tumour of the scapula clinically diagnosed as chondrosarcoma revealed plasmacytoma with amyloid on histology. Another case of kala-azar presented with features akin to that of PCD and one case had dual malignancies. Such a high incidence of PCDs with varied picture in a short time is not usually seen in other parts of this country; a fact which may be due to lack of awareness.

Antral diaphragm with achalasia cardia.

A 50-year-old woman presented with gastric inlet and outlet obstruction due to achalasia cardia and antral mucosal diaphragm, respectively. The diagnosis was based on typical radiological features, endoscopy and full-thickness histology of biopsy at postmortem.

Burns in elderly patients.

Admissions in the burn unit of IPGME & R, Calcutta over a period of 5 years from 1985 to 1990 have been reviewed. There were 1980 patients who had been treated and 84 of them were of 60 years of age or above. Mortality rate in elderly patients with burns had been found to be much higher. High mortality rate might be due to pre-existing medical problems and low general condition due to aging. Most of them were treated with conservative surgery. Early excision and grafting was the surgical approach in few cases with discouraging results.

Malignant rhabdoid tumour of kidney. A case report.

A case of malignant rhabdoid tumour of kidney is reported. Interesting features are bony metastasis at presentation and FNAB diagnosis of metastasis.

Malpighian corpuscles of spleen in infancy and childhood.

In early infancy splenic white pulp is seen arranged around the central arterioles. They do not show any reactive changes even in the presence of systemic infections. Lymphoid follicles are seen at 6 weeks of life. Germinal centres appear from the 8th week of life onwards. Periarteriolar lymphocytic sheaths persist in the older children along with the reactive changes.

Histomorphological criteria for prognosis in breast cancer.

One hundred cases of carcinoma breast were analysed with regard to histological features and clinical follow-up. Bad prognostic factors included tumour size larger than 5cms; absent or minimal intraduct component in the tumour and absent or minimal periductal elastosis. Conversely significant intraduct component in the tumour and periductal elastosis were associated with better survival. Degree of lymph nodal involvement did not influence the outcome. One reason for this unexpected finding could be that patients with more than 3 lymph node involvement were given additional chemotherapy.

Outbreak of Salmonella worthington meningitis & septicaemia in a hospital at Chandigarh (north India).

During August 1988 an outbreak of hospital acquired infection due to S. worthington has been reported at the Nehru Hospital, Postgraduate Institute of Medical Education and Research, Chandigarh. A total of seven neonates presented with the clinical features of meningitis and septicaemia during this outbreak and six babies died. S. worthington was isolated from blood and cerebrospinal fluid respectively. The same strains were isolated from the baby warmer mattress, baby cot, suction machine bottle and wall of the fridge. Samples from doctors, nurses and apparently healthy babies born during this period did not grow the above organism. This appears to be the first report on S. worthington in human beings from India. The outbreak was controlled by thorough cleaning and fumigation. The organisms were also mostly sensitive to antibiotics used, in contrast to the multiple drug resistant pattern reported from elsewhere.
