Expression Pattern of Estrogen Receptor Alpha and Progesterone Receptor in Gallbladder Carcinoma and Their Association with Clinicopathological Parameters and Overall Survival.

BACKGROUND: Gallbladder cancer (GBC) is a highly aggressive malignant tumor with a poor prognosis. Despite being first described two centuries ago, there are no targeted therapies available beyond conventional cytotoxic therapy. Epidemiological studies have shown that the incidence of gallbladder cancer is higher in females than males. This suggests that the gallbladder may be a female sex hormone-responsive organ, and these hormones might be involved in the pathogenesis of gallbladder cancer. Therefore, we aimed to analyze the expression of ERα and PR in GBC and correlate their expression with clinicopathological variables and overall survival. PATIENTS AND METHODS: A total of 235 histopathologically diagnosed GBC cases were included in this hospital-based cross-sectional study. Clinicopathological data were collected, and the expression of ERα and PR was evaluated by immunohistochemistry. RESULTS: The mean age of this study population was 55.47 ± 8.45 with range 28-87 years. Females were predominated over male with a male-to-female ratio of 1:3.5. Positive nuclear expression of the ERα and PR was found in 13 (5.5%) and eight (3.4%) cases, respectively. Apart from nuclear staining, cytoplasmic expression of ERα and PR was found in three (1.2%) and 31 (13.2%) cases, respectively. Higher percentage of positive nuclear expression of ER was found in < 50 years age (p value = 0.04), parity > 4 (p value = 0.02), advanced pT stage (T3) (p value = 0.01), lymphovascular invasion (p value = 0.02), and liver invasion (p value = 0.04) which were statistically significant. Higher percentage of PR expression was also observed in < 50 years age (p value = 0.01), and tumor associated with gallstone (p value = 0.04). There was no significant correlation between cytoplasmic expression of ER, PR, and clinicopathological variables. In multivariate analysis, there was no significant correlation between ER or PR positive expression and overall survival. CONCLUSION: Although nuclear expression of ERα was significantly associated with progressive disease factors but the positive expression was found in very small percentage of GBC cases. So anti-hormone therapy might be an option in patient with ER α positive gallbladder carcinoma.

Intracranial tumor-to-tumor metastasis in an elderly female: An unusual case report.

Tumor-to-tumor metastasis is an extremely rare event, with only 150 reported cases in the literature. Meningioma, renal carcinoma, and tumors of the thyroid are the commonest sites of metastasis. Lung, breast, and GI-tract cancers are the most common types that undergo metastasis. Meningioma is the most common intracranial tumor as recipient of the tumor-to-tumor metastasis. Although breast carcinoma is the most common tumor to metastasize, adenocarcinoma from other organs can also spread to meningiomas, like the ovary and upper gastrointestinal (GI). We report a case of adenocarcinoma metastasis to meningioma with the possibility of primary involvement of the ovary or upper GI. A 77-year-old female patient presented to neurosurgery with episodes of multiple seizures and loss of consciousness. An MRI suggested a left frontotemporal meningioma. The patient underwent craniotomy with mass dissection. Microscopic examinations showed a dual tumor containing both components of meningioma with a metastatic adenocarcinomatous component. The tumor cells were positive for cytokeratin (CK7). Thus, the final diagnosis was made as meningothelial meningiomas (WHO grade I) with metastatic mucinous adenocarcinoma, possible primaries of the ovary or upper GI tract. The patient could not be followed up as we lost the patient a few days after surgery.

Role of perigastric arcade removal in serous epithelial ovarian cancers.

Introduction: Omentectomy is an essential part of cytoreductive surgery (CRS). However, removal of perigastric arcade (PGA) of the omentum is a controversial aspect of omentectomy in view of the fear of injury, vascular compromise and gastroparesis. Hence, we conducted a study to evaluate the necessity and effect of removal of PGA during omentectomy. Methods: The nature of the study was a prospective observational study. The study period was for 1 year between 1.3.2019 and 29.2.2020. Patients with stage III to IV serous epithelial ovarian cancers - chemo naive/post neoadjuvant chemotherapy, without macroscopic involvement of the PGA were included in the study. Patients were divided into two groups - those who had PGA removed (group 1) and those whose PGA was preserved (group 2). Pre, intra and postoperative factors between the two groups were compared using standard statistical methods. Results: Micrometastasis to PGA was present in 36.4% of the patients in group 1. The predictors for this involvement included gross involvement and microscopic involvement of the mobile part of the omentum (p < 0.001), pre surgery Meyer's score (p < 0.05) and requirement of peritonectomy (p < 0.05) during the CRS implying that higher the peritoneal carcinomatosis, more are the chances of microscopic involvement of PGA. On comparing postoperative outcomes between the two groups, we noted a statistically significant difference in intra-operative time (p < 0.01), prolonged recovery time with increased intensive care unit and hospital stay (p < 0.001) in group 1, although all with small absolute difference. However, there was no significant difference in major post-operative complications or time taken to tolerate soft diet. Conclusion: Micrometastasis to PGA was noted in significant number of cases. Its removal is also a safe procedure with minimal morbidity and good postoperative outcomes especially in cases with significant peritoneal carcinomatosis. Hence, it should be considered, provided we are achieving a complete cytoreduction otherwise.

Reproducibility of Cytomorphological Diagnosis and Assessment of Risk of Malignancy of Thyroid Nodules Based on the Bethesda System for Reporting Thyroid Cytopathology: A Tertiary Cancer Center Perspective.

Introduction: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was introduced for unifying the terminology and morphologic criteria along with the corresponding risk of malignancy, leading to more consistent management approaches. The aim of this study was to study the utility and reproducibility of TBSRTC in reporting thyroid cytology in a referral cancer center. Methods: The fine-needle aspiration (FNA) of all thyroid nodules were included for a period of 5 years, from January 2016 to December 2021, in this cancer center. They were retrospectively reviewed and recategorized according to TBSRTC by two experienced pathologists. Cytohistopathological correlation was done for the cases which underwent surgical resection. Results: 522 fine-needle aspiration cytology (FNAC) of thyroid swellings were evaluated and categorized according to TBSRTC. There was agreement in the cytological diagnosis of 512 cases, of which 260 (50.78%) were benign lesions, 189 (36.91%) were malignant, 5 (0.97%) were unsatisfactory/nondiagnostic, 41 (8.01%) were follicular neoplasm/suspicious for neoplasm, 13 (2.53%) were suspicious for malignancy, and 4 (0.78%) cases were reported as atypia of undetermined significance. Two cytopathologists were in agreement in 512 cases (98%) of cases. Almost complete concordance was noted in the malignant (99%) and benign categories (98%). Disagreement was seen in 10 cases. Histological follow-up was available in 201 cases with an overall malignancy rate of 62.68% (126/201). Conclusion: TBSRTC proved to be a very simple and effective reporting system for thyroid FNAC, especially in the setting of a cancer center. This enables proper triaging of cases with thyroid masses into those who require surgical intervention and those who can avoid it, thereby preventing unnecessary morbidity.

Diagnostic Utility of Ultrasound-Guided Fine-Needle Aspiration Cytology in Gall Bladder Lesions: An Experience from a Tertiary Care Cancer Center in Eastern India.

INTRODUCTION: Gallbladder cancer (GBC) is the most common malignancy, representing 80-95% of biliary tract cancers. Although ultrasonography-guided fine-needle aspiration cytology (USG-FNAC) has emerged as an effective diagnostic the tool for the precise diagnosis of gallbladder lesions, data on its diagnostic utility and cytomorphological categorization of gallbladder lesions are lacking. AIMS: To study the diagnostic utility of USG-FNAC in gallbladder lesions. MATERIALS AND METHODS: This study was the conducted prospectively on patients who came with clinical and radiological evidence of gallbladder space-occupying lesion and then advised to USG-FNAC over 2 years and 6 months from January 2018 to June 2020. RESULTS: A total of 314 cases were included. The mean age was 56 years, with a range of 17-88 years. Women predominated over men (Male:Female = 1:2.3). Primary adenocarcinoma of the gallbladder was most common. On cyto-histological correlation, the sensitivity, specificity, and diagnostic accuracy of USG-FNAC of gallbladder lesions were found to be 98.82, 87.23, and 96.3%, respectively. CONCLUSION: The USG-FNAC of gallbladder lesion was found to be an easy, quick, cost-effective, and presumptive diagnostic procedure. It should be opted as an initial preoperative diagnostic modality in high incidence areas to avoid inappropriate management with unnecessary morbidity and cost. Moreover, a close cytological examination of the architectural pattern and the cytomorphological features would help in the sub-typing and prognosticating the tumor.

Geographical distribution of cervical cancer in Odisha: A 5-year retrospective study at a regional cancer center.

BACKGROUND: Cancer cervix and breast are the two major female health problems in India. A hospital-based, 5-year (2010-2014) retrospective study was conducted at a regional cancer center of Odisha to analyze the present burden of cancer cervix in this state, which has a population of more than 45.5 million at present. MATERIALS AND METHODS: All the patients suffering from cancer cervix that was treated by radiotherapy during 2010-2014 at this center were analyzed year wise for age, stage of disease, and native area. RESULTS: Based on the Census 2011 data, it was calculated and found that from the low-literacy area on an average of 4.62 cervical cancer patients per million, from the medium-literacy area 6.56 patients per million, and from high-literacy area 19.11 patients per million of population have received radiotherapy in this hospital. More than 60% of patients with cervical cancer were from stage IIIB and in the age group of 50-55 years. DISCUSSION: Odisha has 83.7% female population in rural areas with literacy rate below 50%. Due to lack of awareness and unavailability of cancer care facilities at their reach, they mainly depend on various alternative medicines in unscientific manner for their health care. CONCLUSION: Strengthening of existing regional cancer center, development of oncology wings in all medical college hospitals by providing basic radiotherapy facilities, emphasizing more on district cancer control programs, decentralizing of NGO schemes, and facilitating with more cancer screening and awareness programs may help better registration, prevention, and treatment of cancer in Odisha.

Clinicopathological study of malignant melanoma in a regional cancer center.

BACKGROUND: : Malignant melanoma is a tumor of melanocytic origin. Although uncommon in India as compared with the west, its prevalence is increasing. OBJECTIVES: To document the pattern of clinicopathological features of malignant melanoma cases attending in a regional cancer center in eastern India. MATERIAL AND METHODS: The present study was a retrospective study of 182 cases diagnosed histopathologically as malignant melanoma during 2011-2016. RESULTS: Out of the total cases, 170 (93.4%) were cutaneous and 12 (6.6%) were noncutaneous melanoma. The most common age group was sixth decade with a male predominance. Conventional melanotic melanomas were 176 (96.70%), and only 6 cases (3.30%) were amelanotic melanoma. Among noncutaneous melanomas, 6 were in anorectum, 2 in conjunctiva, and 1 case each in nasal cavity, palate, gingivo-buccal sulcus, and vagina. The acrallentigenous type was the most common variety, and the mixed epithelioid and spindle cell type was the most common histopathological pattern. Clark's level III was the most common level of invasion. CONCLUSION: The lower extremity is the most common site for melanoma, whereas extracutaneous melanomas are exceedingly rare and aggressive neoplasms. Melanoma can metastasize to regional lymph nodes, however, visceral metastasis to liver can also occur. In the absence of pigment in amelanotic melanoma, immunohistochemical markers such as HMB 45 can be used for definitive diagnosis.

Role of fine-needle aspiration cytology in diagnosis of disseminated histoplasmosis in an immunocompetent patient: A case report.

Histoplasmosis is a mycotic infection caused by dimorphic fungus, Histoplasma capsulatum. The organisms are usually found within the cells (macrophages). This organism mostly affects lungs in immunocompetent individuals and disseminated forms are seen in immunocompromised cases. Here, we describe a case of disseminated histoplasmosis in an immunocompetent, 35-year-old female with lymphadenopathy diagnosed by fine-needle aspiration cytology and cell block.

Utility of Tru-Cut Biopsy of Breast Lesions - An Experience in a Regional Cancer Center of a Developing Country.

INTRODUCTION: Tru-cut Needle Biopsy (TCB) is an integral part of triple assessment of breast cancer, which includes clinical assessment, mammography and TCB or Core Needle Biopsy (CNB). The technique is reliable, simple, and reproducible, and inexpensive, which can be adapted even for low-income group of patients and in developing countries. AIM: This study was done to establish the efficacy of TCB of palpable breast lesions in a developing country where mammography is not possible in all cases. MATERIALS AND METHODS: A retrospective analysis of 892 TCBs was done in AH Regional Cancer Centre, Cuttack, Odisha, India where TCBs were performed in patients presenting to outpatient department with palpable breast lesions. The H&E stained sections were interpreted by pathologists of the same centre. Diagnosis was classified into different categories. Immunohistochemistry (IHC) for Estrogen Receptor (ER), Progesterone Receptor (PR) and Her-2/neu was done and interpreted by Allred scoring system. RESULTS: A total 892 TCBs were analysed with 23 repeat TCBs. There were 13 (1.4%) male patients. A total of 747 cases (83.6%) were diagnosed as malignant, including 735 carcinomas, nine malignant phyllodes tumour, two angiosarcoma and one case of Non-Hodgkin' Lymphoma (NHL). It was possible to diagnose special histological types such as lobular carcinoma, metaplastic carcinoma and mucinous carcinoma on TCB. A total of 21 cases were diagnosed as carcinoma on repeat biopsy. Eight of the 735 TCBs diagnosed as carcinoma were bilateral breast cancers, hence actual number of carcinoma cases were 727. IHC was done successfully on the paraffin blocks in 260 cases. In this series out of 727 patients of carcinomas 30% were in young, i.e., below 40 years of age, including four cases of carcinoma below 20 years. There were no false positive case in this study giving a specificity of 100% and sensitivity was 97%. CONCLUSION: TCBs are well tolerated by patients, can be done in OPDs and reduce cost. It is possible to give histological diagnosis of carcinoma, lymphoma, phyllodes tumour and sarcomas on TCBs. The paraffin blocks of TCBs can be used for IHC study which helps the oncologists for preoperative adjuvant therapy.

Management of Chemoradiation-Induced Mucositis in Head and Neck Cancers With Oral Glutamine.

PURPOSE: Head and neck cancers are the third most common cancers worldwide. Oral mucositis is the most common toxicity seen in patients who receive chemoradiation to treat head and neck cancer. The aim of this study was to evaluate the efficacy and safety of oral glutamine supplementation in these patients. MATERIALS AND METHODS: From December 2013 to December 2014, we randomly assigned to two arms 162 patients who had squamous cell carcinoma of the head and neck. Patients in arm A were given oral glutamine once per day, whereas those in arm B served as negative control subjects. All patients received radiotherapy given as 70 Gy in 35 fractions over 7 weeks with an injection of cisplatin once per week. Patients were assessed once per week to evaluate for the onset and severity of mucositis, pain, use of analgesics, and for Ryle tube feeding. RESULTS: We observed that 53.1% of patients developed mucositis toward the fifth week in the glutamine arm compared with 55.5% of patients in the control arm at the third week. None in the glutamine arm compared with 92.35% of patients in the control arm developed G3 mucositis. Rates of adverse events like pain, dysphagia, nausea, edema, and cough, as well as use of analgesics and Ryle tube feeding, were significantly lower in the glutamine arm than in the control arm. CONCLUSION: This study highlights that the onset as well as the severity of mucositis in patients receiving glutamine was significantly delayed. None of the patients receiving glutamine developed G3 mucositis. Hence, the findings emphasize the use of oral glutamine supplementation as a feasible and affordable treatment option for mucositis in patients with head and neck cancers who are receiving chemoradiation.

Role of fine needle aspiration cytology and cell block in diagnosis of scar endometriosis: A case report.

Presence of endometrial glands and stroma in places other than the uterus is called endometriosis. It can be pelvic or extra-pelvic. Abdominal scar endometriosis is an extra-pelvic endometriosis that can occur after surgery involving the uterus. Post-caesarean section, scar endometriosis is a rare event. The diagnosis is frequently made only after excision of disease tissue. We present a case of post-caesarean section abdominal scar endometriosis presenting as a tumor on the abdominal wall, which was diagnosed by fine needle aspiration cytology and confirmed by cell block preparation.

Synchronous adenocarcinoma and mucosa-associated lymphoid tissue lymphoma of the colon.

Mucosa-associated lymphoid tissue (MALT) tumors are a distinct subtype of non-Hodgkin's lymphoma. Synchronous appearance of adenocarcinoma and colonic MALT lymphoma in the same patient is quite rare. In the present report, we describe a 68-year-old female who presented with a history of bleeding per rectum. She had no history of fever, loss of weight or drenching night sweats. Rectal examination revealed no abnormality. Colonoscopy showed a large ulceroproliferative mass arising from the hepatic flexure, biopsy of which came out to be adenocarcinoma of colon. A right hemicolectomy was performed and microscopic study revealed the tumor type to be synchronous adenocarcinoma with lymphoma. The final diagnosis of this patient turned out to be a synchronous manifestation of both colonic adenocarcinoma and colonic MALT lymphoma. Although the patient remains asymptomatic two years after surgery, the case highlights the therapeutic dilemma that prevails in the definitive management in such scenarios.

Cytologic detection of tuberculous cervicitis: a report of 7 cases.

BACKGROUND: Tuberculous infection, which is now uncommon in western society, is still frequently observed in Third World countries like Africa and India. The cervix is involved in 5-10% of cases in female genital tract tuberculosis. Tuberculous involvement of the female genital tract in almost all cases is secondary to extragenital tuberculosis. There is a relative immunity of the cervix to tuberculosis. Cervical tuberculosis is considered to be rare, and a few well-documented cases of tuberculous cervicitis have been described. Cases of tuberculous cervicitis are often clinically diagnosed as carcinoma of the cervix since the punctation and mosaic pattern observed on colposcopic examination leads to an erroneous impression of malignancy. CASES: Seven cases, clinically suspected to be carcinoma of the cervix, were diagnosed as tuberculous cervicitis from cervical smears. CONCLUSION: Cases of tuberculous cervicitis can mimic cervical cancer, and those cases should be evaluated carefully for accurate diagnosis and proper management of this nonneoplastic condition of the cervix, especially in developing countries where tuberculosis is endemic.

Acute myelogenous leukemia following treatment of invasive cervix carcinoma: a case report and a review of the literature.

Second malignancy is one of the late complications of long-term cancer survivors, treated with radiation or chemotherapy. Here is a case report on acute myelogenous leukemia, which developed after 63 months following the completion of treatment with surgery and platinum-based chemoradiation in a patient of carcinoma cervix IB. The above-mentioned second malignancy is one of the late sequelae of platinum-based chemoradiation. This case is reported here for documentation because of its rarity.

Proliferating Brenner tumour of ovary--a case report.

Transitional cell tumours or Brenner tumours of ovary are uncommon neoplasms. Out of all the Brenner tumours less than 2% are either proliferating or malignant type. Borderline or malignant tumours occur in women who are on an average 10 years older than those with benign tumours. It is essential to categorise these tumours as benign, borderline or malignant type as the biologic behaviour and choice of surgery differs in all of the three categories. The gross and microscopic findings of a proliferating brenner tumour are reported here.

Hepatoblastoma--report of three cases.

Hepatoblastoma accounts for only 0.5% of all paediatric tumours. The vast majority of these cases are seen under five years of age and a third of patients have some form of congenital anomaly syndrome or other childhood tumour. Most recent classification describes six subtypes of hepatoblastoma. Surgical resection is the best treatment preceded by accurate staging and chemotherapy or radiotherapy. Hepatoblastoma can be diagnosed by Fine Needle Aspiration Cytology (FNAC). We report here three cases of hepatoblastoma diagnosed by FNAC and subsequently confirmed by histopathology following resection of hepatic tumours.
