Radical cystectomy is long considered as the "gold standard" in the management of localized muscle-invasive bladder cancer (MIBC), and curative intent radiotherapy is relegated to those with either inoperable tumors or with multiple co-morbidities precluding surgery. This is despite a large volume of data showing equal survival between the two modalities of treatment in this setting. In this work we seek to dispel some common myths surrounding curative intent radiotherapy as part of a bladder preservation strategy in MIBC. Baseless claims of inferior outcomes and perceived contraindications for bladder preservation are debunked along with unfounded doubts relating to hypofractionation. Finally, we caution against using response to neoadjuvant chemotherapy as a predictive biomarker for treatment selection and conclude by recommending that trimodality bladder preservation be offered as a therapeutic option that is in clinical equipoise with radical cystectomy.

Highlights • The patient-reported outcomes are as vital as the physician documented toxicities. • The QOL scores return back to normal in most scales similar to baseline value by 3 months. • VMAT based SIB is a feasible and safe strategy in terms of toxicity profile., Objective To assess the change in the quality of life (QOL) in head and neck cancer patients treated with Simultaneous Integrated Boost (SIB) by Volumetric Modulated Arc Therapy (VMAT) technique. Methods Thirty patients with localised head and neck cancers (Stage II- IVa) were treated with VMAT and SIB technique. The three-dose levels prescribed were 68.2 Gy at 2.2 Gy/fraction, 62 Gy at 2 Gy/fraction and 55.8 Gy at 1.8 Gy/fraction to the high, intermediate and low-risk volumes respectively. Concurrent chemotherapy with cisplatin 100 mg/m2 was administered once in three weeks. Acute toxicities were evaluated and scored according to the RTOG grading system. Quality of life (QOL) was assessed using European Organization of Research and Treatment of Cancer (EORTC) QLQC30 and HN35 questionnaires at baseline and in three instances (immediately, one month and three months after the radiotherapy). Results Out of the total 30, 80% patients had a complete response (CR) at the median follow up of 12 months, while three patients died because of progression, and the remaining 3 had stable disease. All planning objectives were achieved for organs at risk and planning target volume(PTV). There was a statiscally significant(p value

Background: Pancreatic cancer is a devastating disease with a 5-year survival rate of 5–10%. Radiation is commonly used in neoadjuvant and adjuvant settings to improve local control. Studies have shown that circulating lymphocyte count depletion after radiation has been associated with poor tumor control and inferior overall survival (OS) outcomes. Method: To better understand the impact of radiation-associated lymphopenia in pancreatic cancer, the authors undertook this systematic review and meta-analysis of clinical studies that have reported radiation-related lymphopenia in pancreatic cancer. Results: A systematic methodology search of PubMed, Embase and the Cochrane Library resulted in 2969 abstracts. Nine studies fulfilled the inclusion criteria. Six studies reported on outcomes in patients undergoing definitive chemoradiation and three studies comparing outcomes in stereotactic body radiotherapy versus definitive chemoradiation. The patients with severe lymphopenia were at increased risk of death with a pooled hazard ratio of 2.33 (95% CI: 1.79, 3.03; I2: 36%; p 2: 95%; p 2: 99%; p

335 Background: The RECORD Study is a real world data, prospective evaluation of clinical outcomes in patients with nmCRPC treated with Darolutamide. This study will increase the understanding of treatment response and management and in particular inform regarding use of next generation imaging in this setting. Methods: Patient data from 9 UK centres was collected based on the recommendation of NICE for Darolutamide as an option for the treatment of non-metastatic castrate resistant prostate cancer (nmCRPC) from November 2020. Data cut-off was 15 September 2022. The study is ongoing. Results: 87 patients were analysed with a median age of 78 (range 61-92). Median pre-treatment PSA and PSA doubling time (PSAdT) were 13 (range 1.99-110.6) mg/L and 5.05 (range 0.6 - 10) months. 42 patients (49.4%) had pre-treatment PSAdT of

Background The impact of radiation-related lymphopenia on clinical outcomes has been reported in various solid malignancies such as high grade gliomas, head and neck cancers, thoracic malignancies and gastro-intestinal malignancies but its impact is not clearly known in the context of common genito-urinary (GU) malignancies. Methodology To better understand the effect of radiation-associated lymphopenia in prostate and bladder cancer, we undertook this systematic review of clinical studies that have studied radiation-related lymphopenia in GU malignancies. A systematic methodology search of PubMed, Embase, and Cochrane library resulted in 2125 abstracts. Ten studies fulfilled the inclusion criteria which included any prospective, retrospective study or cohort study of prostate, urinary bladder, kidney, ureter, urethra, penile cancer in humans, and radiation should be part of treatment and intent has to be in definitive or adjuvant settings. Finally the study should have data on radiation-related lymphopenia. Results Four studies reported on the cancer-specific outcomes related to the lymphopenia. The incidence of low lymphocyte counts were documented in all the studies. Three studies analyzed the factors associated with the Lymphocyte depletion. Pooled incidence of severe lymphopenia was 29.25% and mild to moderate lymphopenia was 60.75%. Bone marrow volume receiving 40 Gy was associated with the incidence of lymphopenia. Conclusion One-third of the patients suffer from severe lymphopenia after radiation in prostate and bladder cancer. There are no clear data to support the correlation between severe lymphopenia and disease outcomes. Bone marrow dosimetry can affect the incidence and severity of lymphopenia. There is need of prospective datasets to identify the impact of radiation-related lymphopenia in GU malignancies focusing on long-term side effects, recurrence rates, and overall survival.

Despite the modern advances in treatment techniques, the survival of locally advanced lung cancer patients continues to remain poor. Circulating lymphocytes have an important role to play in local immune response to RT as well as immune checkpoint inhibitors, and radiation related lymphopenia has been associated with inferior survival in various tumors.We undertook this systematic review and meta-analysis to evaluate the literature on risk and impact of lymphopenia in thoracic tumors. A systematic methodology search of the PubMed, Embase and Cochrane library was performed and eligible studies selected based on pre-defined inclusion and exclusion criteria. Review Manager Version 5.4.1 was used for the meta-analysis.Fourteen studies were included in the final systematic review and 10 in the quantitative analysis. Overall mean incidence of severe lymphopenia (absolute lymphocyte count 500) was 64.24%. The patients with severe lymphopenia were at increased risk of death with a pooled HR of 1.59 (95% CI: 1.40, 1.81, IRadiation related lymphopenia is associated with increased hazard of progression and death in lung cancer. Minimizing the lung and heart dose, especially in patients with concurrent other risk factors can reduce lymphopenia and potentially improve treatment outcomes in these patients.

Background Cancer patients with COVID-19 disease have been reported to have double the case fatality rate of the general population. Materials and methods A systematic search of PubMed/MEDLINE, Embase, Cochrane Central, Google Scholar, and MedRxiv was done for studies on cancer patients with COVID-19. Pooled proportions were calculated for categorical variables. Odds ratio and forest plots were constructed for both primary and secondary outcomes. The random-effects model was used to account for heterogeneity between studies. Results This systematic review of 31 studies and meta-analysis of 181,323 patients from 26 studies involving 23,736 cancer patients is the largest meta-analysis to the best of our knowledge assessing outcomes in cancer patients affected by COVID-19. Our meta-analysis shows that cancer patients with COVID-19 have a higher likelihood of death (odds ratio, OR 2.54), which was largely driven by mortality among patients in China. Cancer patients were more likely to be intubated, although ICU admission rates were not statistically significant. Among cancer subtypes, the mortality was highest in hematological malignancies (OR 2.43) followed by lung cancer (OR 1.8). There was no association between receipt of a particular type of oncologic therapy and mortality. Our study showed that cancer patients affected by COVID-19 are a decade older than the normal population and have a higher proportion of co-morbidities. There was insufficient data to assess the association of COVID-directed therapy and survival outcomes in cancer patients. Despite the heterogeneity of studies and inconsistencies in reported variables and outcomes, these data could guide clinical practice and oncologic care during this unprecedented global health pandemic. Conclusion Cancer patients with COVID-19 disease are at increased risk of mortality and morbidity. A more nuanced understanding of the interaction between cancer-directed therapies and COVID-19-directed therapies is needed. This will require uniform prospective recording of data, possibly in multi-institutional registry databases.

Ovarian cancer patients presenting with breast metastasis are a rare phenomenon. Very few cases have been documented so far in the literature and have shown that long-term prognosis of these patients is poor despite intense chemotherapy schedules. This report discusses a case of high-grade serous carcinoma of the ovary with metastases to the right breast and axilla in a 49-year-old female as the first case in the authors’ centre in South India. Additional immunohistochemistry markers were checked to confirm the diagnosis. The patient was on the third line of chemotherapy in December 2015. It is strongly emphasised that breast examination should be routine in all cases of ovary malignant tumours. IHC markers may differentiate between second primary versus metastatic secondaries in the breast. Further clinical trials using novel chemotherapy and systematic review of all case reports may help to form uniform consensus guidelines for these rare entities.
