Endometrial stromal sarcoma with sex cord differentiation is a very unusual neoplasm affecting the uterine cavity with an incidence of only 0.25%. They can cause difficulties in diagnosis due to it is histologic appearance and rarity of occurrence. Histopathological diagnosis still remains the cornerstone of diagnosis. Immunohistochemistry and molecular studies are also very helpful. We report a case of a 47-year-old patient who was diagnosed clinically and radiologically as intramural leiomyoma, but on histopathology examination and immunohistochemically proved to be endometrial stromal sarcoma with sex cord differentiation.Follicular T-cell lymphoma is a recently described, rare neoplasm with the true incidence still unknown. It is a lymph node-based tumor in which the node shows a follicular pattern of growth. Immunohistochemistry confirms the cells of origin to be follicular helper T-cells and thus plays an important role in the diagnosis of the tumor. We report a case of follicular variant of peripheral T-cell lymphoma, which was erroneously reported as Hodgkin lymphoma on fine-needle aspiration, and follicular lymphoma on hematoxylin and eosin.Oral malignant melanomas are rare neoplasms of the oral cavity which present significant diagnostic ambiguity. The etiology is unclear though the stimulation of melanoblasts by genetic, epigenetic, and traumatic causes that have been proposed in etiopathogenesis. Clinically, it presents as a pigmented swelling or growth which remains asymptomatic until it advances to later stages. It is highly invasive and metastasizes quickly; hence, it has a very poor prognosis with a survival rate of only 7%. Navitoclax manufacturer Early diagnosis of the neoplasm and thorough investigation is not only necessary for prompt treatment but also necessary for a favorable prognosis.Patients who develop metastatic arthritis secondary to solid tumors are rare. It is even more uncommon to be a presenting symptom. We present a case where a known case of osteoarthritic patient presented with complaints of knee swelling secondary to primary colonic carcinoma with lung metastasis. It was initially diagnosed on histopathology examination as metastatic adenocarcinoma from excised synovial mass and further investigated for primary carcinoma. Later, computed tomography was done and found out the primary colonic carcinoma arising from transverse colon along with lung metastasis.Due to the prolongation of a lifetime, more cancer patients with cardiac implantable electronic devices are treated by radiotherapy. However, radiation may cause permanent or temporary malfunctions on these devices, and new-generation devices are more sensitive to radiation. Besides, radiotherapy techniques and image guidance methods that may cause different interactions with the functions of the devices have been changed significantly recently. Here, we reported our clinical experience in a patient with a pacemaker who underwent radiotherapy with intensity-modulated radiation therapy (IMRT) due to gastric cancer and reviewed the literature.Primary squamous cell carcinoma of the rectum is a very rare malignancy in clinical practice. There are only a few case-studies related to SCC rectum in HIV-1 infected persons in the literature. We report here a case in which the patient, in spite of receiving combination antiretroviral therapy and optimum virological control, suffered from SC C rectum. He was treated with chemoradiation but he relapsed soon and now receiving palliative treatment with Cisplatin and Fluorouracil. There are no case-reports on this issue from India and probably this is the first case-report on SCC rectum in HIV-1 infection adequately treated with cART. Since this is very aggressive disease, outcome is poor.Colorectal carcinoma (CRC) is one of the most frequently diagnosed malignancies worldwide with a high mortality rate. CRC is often plagued with significant treatment-related morbidity and mortality, and metastatic progression is common. With the advent of immunotherapy, inoperable and advanced cancers have shown favorable response. Immunotherapy has paved the way for survival of all those with advanced metastatic disease whose treatment was limited to palliative care. We explore the case of a 28-year-old female with advanced metastatic CRC refractory to chemotherapy and targeted therapy, managed with PD-1 inhibitor with complete clinical and pathological response in a relatively short period of time. The notion of upfront immunotherapy for advanced metastatic CRC with microsatellite instability is definitely reinforced by the favorable response seen in our case, and we hope that these findings would help reduce the dependence on chemotherapy as the mainstay therapeutic for advanced CRC.
The medicinal properties of Syzygium sp., especially the antidiabetic property, date back to the ancient times. However, in the recent past, extracts from different parts of the Syzygium sp. have demonstrated promising anticancer activities in diverse cancer types, and now, attempts are being made to identify the active phytochemicals.
In this study, we intended to test the anticancer properties of phytochemicals extracted from the fruit of Syzygium cumini plant in ovarian cancer cells.
A total of nine phytochemicals extracted from the S. cumini fruits using chloroform were tested for their anticancer activity in the ovarian cancer cell line PA-1. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium assay was performed to calculate the 50% inhibition (IC50) concentration and cell cytotoxicity values. Cell scratch assay was performed to assess the proliferation inhibition activity of the phytochemicals. Cisplatin was used as positive control.
Out of the nine phytochemicals tested, qticancer activity of these phytochemicals derived from S. cumini in the ovarian cancer cells. These data suggest that there is a potential to develop these phytochemicals as anticancer therapeutic agents either as monotherapeutic agents or in combination with commonly used chemotherapeutic agents, which needs to be explored.
Coronavirus disease (COVID-19) pandemic has affected the entire health-care system and has led to a sense of fear and anxiety in the minds of patients. Patient's perceptions in this scenario of the pandemic are unknown. Providing continued care for cancer patients during the lockdown has been challenging. Measures are needed to improve patient safety and satisfaction during these challenging times and hence the importance of measuring the degree of satisfaction for the quality of care provided. The aim of the study was to evaluate the factors related to patients' satisfaction and also understand their apprehensions, fears, and anxieties they face as they receive radiotherapy treatment amid COVID-19 pandemic. The study's objective was to explore other aspects such as logistic issues, patient-staff communication, and also perceptions of the patients toward the outbreak.
This study was conducted from April to September 2020. A questionnaire was created for which the patients were asked to provide answers. Pa and anxieties, and also in determining their awareness about the pandemic. The survey was also useful to get the patients' opinion and ideas for improvement in the health-care services.
Biochemical changes in irradiated malignant tissue lead to altered autofluorophores status which should be different for cancerous tissue (residual/recurrence) and irradiated normal tissue. If this irradiated tissue is examined through fluorescent spectroscopy, we can find the spectroscopic changes occurring after the completion of treatment which can be helpful in evaluating treatment response.
Punch biopsy sample was examined through fluorescent spectroscopy in oral cavity cancer patients before and after definitive radiation treatment. The change in spectroscopic pattern before and after radiation treatment was recorded and assessed.
Final analysis was done in 36 samples. In irradiated tissue, it has been observed that there was increase in the intensity of collagen fluorescence. It was found that the Half width half maximum (HWHM) is more in case of preirradiated sample. The decrease in the HWHM in case of irradiated sample shows the decrease in the number of cells (cell density as compared to that in preirradiated sample). These spectral findings are well-explained pathophysiologically and clinically as amount of collagen are increased in irradiated tissues due to loss of cancerous cells and regeneration of collagen cross-links (fibrosis) and reproduction of normal tissue as a response to radiation treatment.
After thorough study in a large number of samples, we may be able in the future to grade the alteration in fluorescence of collagen obtained after radiation treatment in terms of complete, partial, or no response.

Merkel cell carcinoma (MCC) is a rare but highly aggressive neuroendocrine carcinoma of the skin. In this study, we aimed to evaluate the clinicopathologic characteristics, treatment outcomes, and survival of MCC cases in Turkey.
The patients diagnosed with MCC between 1999 and 2018 at twenty different centers in Turkey were included in the study. Patient and tumor characteristics and adjuvant and metastatis treatment outcomes were analyzed retrospectively.
The median age of totally 89 patients was 70 (26-93). The most common primary location was lower limbs (n = 29, 32.5%). Immunohistochemically, CK20 positivity was present in 59 patients (66.3%). Only two patients had secondary malignancy. The majority of the patients (n = 76, 85.4%) were diagnosed at the localized stage. Surgery was performed for all patients in the early stage, and adjuvant radiotherapy or/and chemotherapy was applied to 52.6% (n = 40) of nonmetastatic patients. The median follow-up was 29 months. Recurrence developed in 21 (27.6%) atment were not associated with recurrence.
Vertebral hemangiomas are defined as benign proliferation of blood vessels. Vertebral hemangiomas are generally found incidentally by computerized tomography or magnetic resonance imaging; however, they may also cause pain and quality-of-life impairment in some circumstances with reference to their location and association with the spinal cord. In this study, we assessed the utility of image-guided radiation therapy (IGRT) in the management of patients with painful vertebral hemangioma.
Patients receiving IGRT for the management of painful vertebral hemangioma were evaluated. The total dose was 24 Gy delivered in 12 daily fractions. The verbal numeric scale (VNS) was used for the assessment of pain relief. The median follow-up duration was 13 months (range 6-24 months).
Median preradiotherapy VNS score was 8 (range 6-10) and median postradiotherapy VNS score was 1 (range 0-2) for the total 135 patients treated with IGRT at our department for painful vertebral hemangioma. Reduction in VNS scores after IGRT was statistically significant (P < 0.05).
Our single-center study revealed that IGRT resulted in substantial relief of pain from vertebral hemangioma. Randomized prospective multicenter trials are needed to shed light on the optimal management of patients suffering from pain due to vertebral hemangioma.
