Log ODDS (LODDS) of positive lymph nodes as a predictor of overall survival in squamous cell carcinoma of the penis.

OBJECTIVE: To evaluate the role of logarithmic ODDS (LODDS) in the number of positive lymph nodes and the number of negative lymph nodes as a prognostic metric in the squamous cell carcinoma (SCC) penis. METHODS: Data were retrospectively collected from 96 cases of SCC penis that underwent bilateral groin dissection between 2010 and 2015 at our institute. Lymph node density (LND) and LODDS were calculated for all the patients and classified according to American Joint Committee on Cancer (AJCC) pN staging. Thresholds for LND (24% and 46%) and LODDS (-0.75 and 0) were established. Multivariate analysis of various cofactors was done with overall survival (OS) as a dependent factor. Three classification systems were compared using receiver operative characteristic (ROC) curve analysis. RESULTS: Univariate analysis showed that AJCC pN, LND, and LODDS were all significantly correlated with OS. However, only LODDS (HR, 11.185; p = .023) remained an independent prognostic factor through multivariate analysis. LODDS (log-likelihood = 3832 vs. 3798; p < .001) had better prognostic performance than pN and better discriminatory ability than LND (AIC = 3902 vs. 3928). LODDS had better power of discrimination than LND and pN. LODDS could predict survival in lymph node yield (LNY) < 15 (p < .001). CONCLUSION: LODDS is an independent predictor of OS in the SCC penis and has superior prognostic significance than the AJCC pN and LND classification systems.

Lipoleiomyosarcoma Presenting as Massive Retroperitoneal Mass: An Unusual Soft Tissue Tumor of Abdomen and its Review of Literature.

Lipoleiomyosarcoma is a malignant tumor of both mesenchymal and smooth muscle origin. Lipoleiomyosarcoma is a very rare type of retroperitoneal sarcoma, which by itself is a rare type of soft tissue sarcoma. Lipoleiomyosarcoma is a very rare subtype of liposarcoma, which is the most common type of retroperitoneal sarcoma. To our best review of available literature, this was the first case of lipoleiomyosarcoma presenting as a massive retroperitoneal mass of size 50 × 50 × 30 cm, managed with multi-visceral R0 resection. The computed tomography of the abdomen showed a massive fat density lesion with internal soft density lesions and internal calcifications. Multivisceral resection was planned and executed and achieved R0 resection. We suggest that lipoleiomyosarcoma should be included in differential diagnosis of retroperitoneal tumors, and multi-visceral R0 resection should be considered as an option for lipoleiomyosarcoma, as these tumors have very good prognosis with R0 resection.

The surgical management and oncologic outcomes of patients with fungating soft tissue sarcoma treated at a tertiary cancer centre and review of literature.

Background: Currently there is limited literature available on fungating soft tissue sarcoma and its effect of outcomes. In the current study we evaluated the surgical management and oncologic outcomes of patient with fungating soft tissue sarcoma. Materials and methods: This was a retrospective observational study of patients with fungating sarcoma between January 2015 till January 2019 at a tertiary cancer care centre. A total of 59 patients were considered of which 16 had metastasis at presentation. The duration of symptoms prior to presentation averaged 10.2 months (median, 7.2months; range, 1-57 months). Median tumor length was 10 cm. Results: 56% patients underwent amputation and 44% were treated with limb salvage. Following limb salvage surgery in10 cases primary closure of defect was performed and 6 cases required skin grafting for closure of defect. In 6 patients local flap was used for coverage of defect and 4 patients required free flap surgery. Two-year overall survival (OS) of the study cohort were 52.2% and 58% respectively. Two-year disease free survival (DFS) and OS in 43 non metastatic patients at presentation was seen in 58%(95% CI,38%-74%) and 66.5%(95% CI,42%-81%) respectively. The two-year disease OS in 16 patients with metastasis at presentation was 33.2 %. On univariate analysis, tumor size and metastatic at presentation had significant effect on survival. Conclusion: Tumor size and metastatic at presentation has significant impact on survival in these patients. The oncologic outcomes including Disease free survival, overall survival and local recurrence rates similar amongst the two surgical modalities (amputation versus limb salvage). Amputation rates are more amongst fungating soft tissue sarcoma but limb salvage can be attempted whenever feasible keeping tumor free surgical margins under consideration.

Outcomes of minimal access cytoreductive surgery (M-CRS) and HIPEC/EPIC vs. open cytoreductive surgery (O-CRS) and HIPEC/EPIC in patients with peritoneal surface malignancies: a meta-analysis.

Introduction: Minimal Access Surgery (MAS) has shown better peri-operative outcomes with equivalent oncological outcomes in gastrointestinal and thoracic oncology. Open CRS (O-CRS) procedure accompanies inevitable and significant surgical morbidity in patients. The aim of the review article is to compare outcomes of M-CRS and HIPEC/EPIC with open procedure in peritoneal surface malignancies. Content: Comprehensive search of databases was done and total 2,807 articles were found (2793-PubMed and 14-Cochrane review). PRISMA flow chart was prepared and 14 articles were selected. Meta-analysis was performed according to PRISMA guidelines using random-effects model (DerSimonian Laird) and fixed effect model. Publication bias was tested with Funnel plot and Egger's regression test. Quality of studies was assessed by Newcastle-Ottawa scale. Summary and Outlook: Patients in both groups [total (732), M-CRS(319), O-CRS(413)] were similar in demographic characteristics. Peri-operative outcomes were significantly better in M-CRS group in terms of blood loss SMD=-2.379, p<0.001 (95 % CI -2.952 to -1.805), blood transfusion RR=0.598, p=0.011 (95 % CI 0.402 to 0.889), bowel recovery SMD=-0.843, p=0.01 (95 % CI -1.487 to -0.2), hospital stay SMD=-2.348, p<0.001 (95 % CI -3.178 to -1.519) and total morbidity RR=0.538, p<0.001 (95 % CI 0.395 to 0.731). Duration of surgery SMD=-0.0643 (95 % CI -0.993 to 0.865, p=0.892) and CC0 score RR=1.064 (95 % CI 0.992 to 1.140, p=0.083) had no significant difference. Limited studies which evaluated survival showed similar outcomes. This meta-analysis shows that M-CRS and HIPEC/EPIC is feasible and has better peri-operative outcomes compared to open procedure in patients with limited peritoneal carcinoma index (PCI) peritoneal surface malignancies. Survival outcomes were not calculated. Further studies are warranted in this regard.

Economic Impact of Head and Neck Cancer in India at an Individual Level and the Factors Affecting It.

Head and neck cancer is a significant public health concern in India and globally, with substantial social and economic consequences for affected individuals and their families. The study aimed to assess the socioeconomic impact of head and neck cancer. This paper presents the results of a questionnaire-based study involving 178 head and neck cancer patients who were evaluated at least two years post-completion of their treatment. The questionnaire data collected data on various factors, including site of cancer, treatment modality, speech and diet impairment, changes in earning capacity, occupation, and salary. This was collected from all patients visiting our tertiary cancer care center outpatient department in Ahmedabad, India, between January 2023 and August 2023. The findings highlight the diverse and profound socioeconomic consequences of head and neck cancer. The findings emphasize the need for comprehensive support systems for affected individuals and their families.

Distal Ulna Giant Cell Tumor treated by Resection without Reconstruction: What were the functional outcomes and review of literature.

Introduction: Giant Cell Tumours (GCT) are benign tumours with aggressive potential that disrupt the local bony architecture, which can be especially problematic in peri-articular locations. Our aim was to assess the outcomes of patients with GCT of the distal ulna who were treated by resection without reconstruction. Methods: The study included 21 patients with distal ulna GCT that were treated with resection without reconstruction. There were 12 males and 9 females, with a mean age of 30.4years (range 14-45 years). The patients mean follow-up period was 4.4 years, with a two-year minimum follow-up. Results: Painful swelling was the presenting symtom in all cases. Nineteen patients had Campanacci grade 3 and two had Campanacci grade 2. The mean resected length of the distal ulna was 6.8 cm (range 4-10) cm. The Musculoskeletal Tumor Society score (MSTS) was 26.1. (range 22-28). Grip strength of the affected hand was reduced by 10.5% on average. (range 0%-16%). Two patients were having multi-centric disease on presentation and none of the cases had pathological fracture on presentation. One case had a local recurrence which was treated with surgery. Conclusion: Based on current study, GCT of the distal ulna, en bloc resection without reconstruction can be recommended as a valuable treatment option for Campanacci grades 2 and 3 tumours. Resection of the distal end of the ulna without reconstruction results in excellent functional outcomes, with forearm rotational movement and hand function preserved. According to review of literature this is the largest series of GCT Ulna and we recommend a multicentre and comparitive studies on this topic.

Osteosarcoma of Head and Neck Region: Tertiary Cancer Care Center Experience.

Head and neck osteosarcoma is an uncommon yet aggressive tumor which presents therapeutic challenges to get favourable results. Surgery remained the most effective treatment modality in this entity eventhough chemoradiotherapy have been tried in various studies for better outcome but still not yet becomes the standard in the management of these cases unlike in extremity osteosarcoma. We present our experience in the management of this uncommon yet lethal malignant tumor, i.e. head and neck osteosarcoma. To study the clinicopathological and prognostic features of Osteosarcoma in head and neck subsite. Retrospective study of patients diagnosed with head and neck osteosarcoma between 2003 and 2019. Total of 25 patients were included in our study. Mean age of our population is 27.5 years with slight male predominant. Mandible is the most commonly involved site. Multimodal treatment applied with surgical resection forms the main part in the management. Median DFS and OS were 16 and 36 months respectively with 5 year overall survival of 42%. Out of the various factors studied, absence of surgery, margin positivity are the principle features affecting the prognosis. Head and neck osteosarcoma is generally a jaw bone tumor commonly occurs in young adults with poor outcome. Since there is no universal guidelines to address this uncommon tumor, multiple studies have shown various results in the management. Till date, surgery remained the curative modality with mixed response on the role of chemotherapy and radiotherapy.

Surgery for lung cancer: insight from a state cancer centre in India.

Purpose: Lung cancer is one of the most common cancers in India. However, less than half receive treatment with a curative intent and very few undergo surgery amongst them. We present our surgical experience with non-small cell lung cancer. Methods: A retrospective analysis of a cohort of 92 non-small cell lung cancer patients operated with curative intent. Results: Less than 2% patients of lung cancer were operated on at our centre. Adenocarcinoma was the most common histological subtype. Right upper lobectomy was the most common surgery performed. Two- and 3-year overall survival was 74.3% and 70.6% respectively. Two- and 3- year disease-free survival was 65.4% and 60.8% respectively. Conclusion: The fraction of patients who are operated for lung cancer is very less. There is a definite missed window of opportunity. We have comparable survival to international data.

Differentiated Thyroid Cancers with Synchronous Second Primary Cancers: Case Series.

The incidence of synchronous second primary cancer (SSPC) with DIfferentiated Thyroid Cancers (DTC) is a very rare entity. Very few case reports and case series were published in the literature. To enumerate the clinicopathological data of patients with DTC with SSPC. This is a single-center retrospective study. All the patients diagnosed with DTC and SSPC from January 2016 to July 2023 were included in the study. The demographic, clinicopathological data, and survival data were collected from the institute's database. Twelve patients were found to have DTC with SSPC. All the patients had papillary thyroid cancer. Ten patients had head and neck squamous cell carcinoma, one patient had malignant phyllodes tumor, and another patient had endometrioid adenocarcinoma as the SSPC. Six patients were diagnosed during preoperative evaluation, one patient was diagnosed 3 months after the oral malignancy diagnosis, and five patients were diagnosed with PTC in cervical nodes after neck dissection. Complete thyroid removal was done in six patients and hemithyroidectomy in two patients. The median follow-up was 25.55 months. The median overall survival was 40.97 months. Head and neck SCC is the most common SSPC with DTC. Since these are rare scenarios multi-disciplinary panel discussion can help in deciding management.

Supracarinal lymph node positivity in esophageal squamous cell carcinoma (ESCC) and factors predicting metastasis in supracarinal compartment nodes: Should a total mediastinal node dissection be the standard of care?

Background: Adequate lymphadenectomy in middle- and lower-third esophagus cancer is still a matter of debate. This study aims to find out the extent of histopathological supracarinal lymph nodes positivity rate to establish an adequate lymph node dissection in esophageal squamous cell carcinoma cases operated up-front or after neoadjuvant chemotherapy (CT) + radiotherapy (RT) and its short-term oncological outcome. Materials and Methods: After approval from institutional board review, a retrospective study was conducted from April 2017 to September 2019. A total of 76 patients having mid- or lower-third carcinoma esophagus were operated at our institute for partial/total esophagectomy with extended two-field lymph node dissection were followed. Intraoperative nodal stations were harvested separately and lebeled individually according to the Japanese Esophageal Classification and sent for histopathological examination. Results: The patients had an average age of 52 years. Histologically all were squamous cell carcinoma (SCC). Forty-four patients received preoperative concurrent RT plus drug therapy, whereas 18 cases were operated up-front. Fourteen patients were operated after palliative treatment (CT/RT). The average total lymph node yield was 22 nodes (range 3-69). In 26 patients (34.2%), lymph nodes were positive (N+ disease). Supracarinal nodes were positive in 20 cases (26.31%). The average supracarinal lymph node yield was 10.33 nodes (range 2-32). Five patients (6.5%) had only supracarinal lymph nodes positive on histopathological examination. Seventeen patients had a complete pathological response rate (pCR). Conclusion: In cases of mid-third esophageal carcinoma, extended two fields with supracarinal lymphadenectomy is strongly recommended even after the patient has received neoadjuvant treatment, although the same for lower-third/gastroesophageal (GE) junction tumors should be considered.

Development and Internal Validation of a Nomogram Predicting Overall Survival Based on Log ODDS of Positive Lymph-Nodes for Post Radical Cystectomy Patients in Muscle Invasive Carcinoma of Bladder.

BACKGROUND: To develop and validate a nomogram based on LODDS (Log ODDS of positive lymph-nodes) for prediction of overall survival (OS) in post radical cystectomy (RC) patients of muscle invasive bladder cancer (MIBC). MATERIALS AND METHODS: Data was retrospectively collected from 282 cases of MIBC that underwent RC from 2011 to 2017 at our institute. Significant independent predictors were identified using Cox regression model and incorporated into a nomogram to predict 1, 2, and 4-year OS. RESULTS: Multivariate analysis showed that Neo-Adjuvant Chemo-Therapy (NACT) (P< .001), LODDS (P< .001), T-stage (Pi = .001), CCI (Charlson Comorbidity Index) (P = .034) and grade (P = .003) were independent predictors of OS. The C-index of nomogram (0.740) was higher than that of the American Joint Committee on Cancer (AJCC) staging system (0.614). The bias-corrected calibration plots showed that the predicted risks were in excellent accordance with the actual risks. The results of NRI, IDI, and DCA exhibited superior predictive capability and higher clinical use of the nomogram. CONCLUSION: A simple, easy to use nomogram to predict OS in cases of MIBC has been constructed. To best of our knowledge, LODDS has been incorporated for the first time. It has superior predictive ability and higher clinical use than AJCC system. It would help the clinicians for better patient counselling, planning follow-up strategies and designing a clinical trial for newer adjuvant therapy (eg immunotherapy) in post radical cystectomy patients of MIBC.

Inguinal Lymph-Node Ratio (LNR) as a predictor of Pelvic Lymph-Node Metastasis in squamous cell carcinoma of penis.

OBJECTIVE: To determine the predictors of pelvic lymph-node metastasis in cases of squamous cell carcinoma (SCC) of penis. METHODS: Data was retrospectively collected from 267 cases of SCC penis that presented at our institute between 2009 and 2019. Univariate and multivariate logistic regression models were used to identify independent significant factors. Receiver Operating Characteristic (ROC) curve was used to determine the cut-off of Lymph-Node Ratio (LNR) and discriminative ability of new model. Survival analysis was done using Kaplan Meier Curve. RESULTS: Pelvic Lymph-Node Metastasis (PLNM) was pathologically detected in 56 groins (29.2%). A cut-off of 0.25 was calculated for LNR based on ROC. LNR >0.25 (p = 0.003), ENE (p = 0.037), and LVI (p = 0.043) were found significant on multivariate logistic regression. 71.5% showed PLNM in groins with positive LN (PLN) 0.25 whereas no PLNM was seen in groins with PLN >2 but LNR 0.25, LVI and, ENE are independent predictors of PLNM. The discriminative ability of LNR was better than PLN. PLND could be avoided if no risk factors are present.

Secretory Carcinoma of Salivary Glands: A Case Series and Review of Literature.

Mammary analogue of secretory carcinoma is a recently described entity in WHO 2017 classification of head and neck tumours. It resembles secretory carcinoma of breast. It usually affects the salivary glands and has an indolent behaviour. We reviewed five cases of Mammary analogue of secretory carcinoma in our institute and compared our results with existing literature. All the patients underwent surgical resections and appropriate adjuvant treatment. Immunohistochemistry is an alternative cost effective tool as compared to genetic testing to differentiate secretory carcinoma from its mimickers. Surgery with adequate margins followed by adjuvant therapy is the treatment of choice.

'AJ's Orbicularis Oris Stitch: A Novel and Simple Technique of Reconstructing Central Arch Mandibular Defects in Resource-Constrained Set Up'.

Lip and oral cavity SCC account for 2nd highest incidence of cancers and 3rd most common cause of mortality from cancer in India. Reconstruction of defects of central arch invading cancers results in poor cosmetic and functional outcomes if free flaps are not used. 30 patients with Oral SCC in the age group 20-75 years requiring central arch segmental mandibulectomy were included. Reconstruction was done with pedicled bipaddled PMMC flap with 'AJ's orbicularis oris stitch' using Fiber wire. Patients were divided into 4 groups according to extent of lip and skin loss post excision of primary tumour. Patients were evaluated with subjective scores for drooling, oral competence and cosmesis. There were 4, 12, 9 and 5 patients in Group A, B, C and D respectively. Mean subjective scores using our technique for drooling, oral competence and cosmesis were 3.75/4,3.75/4 and 3.5/4 for group A, 3.45/4, 3.36/4 and 3.09/4 for group B, 2.8/4, 2.6/4 and 2.3/4 for group C defects and 2.5/4, 3/4 and 2.5/4 for group D defects respectively. Over all scores for all patients were 3.2/4, 3.14/4 and 2.84/4 for drooling, oral competence and cosmesis. This simple, quick and inexpensive technique of reconstruction of central mandibular arch defects can drastically improve cosmetic and functional outcomes in a resource restrained set up. However, long term results and comparison studies are required for standardisation of the technique.

Mucosal Malignant Melanoma of Head and Neck: A Case Series from a Single Institute and Review of Literature Abstract.

Malignant melanoma is an aggressive malignancy of melanocytes which is usually found on sun exposed areas of the body. A rare variant of this disease with no etiological association is the mucosal malignant melanoma found on all mucosal surfaces of the body including the oral cavity, respiratory mucosa and anorectal region. In the head and neck region, this disease is almost always diagnosed at an advanced stage and requires a very high index of suspicion for diagnosis. It is more commonly found in females than males.Indians are more prone to this disease as compared to Caucasians.Due to the obscure location within the oral and nasal cavity, it is clinically found at an advanced stage and requires surgical resection with adequate margins for complete eradication. This may be achieved either endoscopically in the nasal cavity or with wide local resection in the oral cavity. this in certain cases may not be feasible due to vicinity of vital structures. In such cases, adjuvant radiotherapy helps in the local control of disease. Histopathological evaluation of the specimen helps to determine aggressive biology of tumor with factors such as presence of ulceration, nodular morphology and perineural invasion being high risk features for development of local and regional recurrence.

Medullary Thyroid Carcinoma: A Single Institute Experience.

Medullary thyroid carcinoma is a rare tumour that is anatomically located in the thyroid gland but is functionally a neuroendocrine tumour. It is usually a disease of older age group but manifests in a young patient in familial form. It is derived from parafollicular c cells and has a predilection for lymph node metastasis. It is associated with slow growth in thyroid gland with early nodal metastasis. Serum calcitonin is useful as a preoperative marker of disease burden and prognosis. In the preoperative period serum levels of calcitonin can guide regarding the need for compartment wise lymph node dissection and the possibility of distant metastasis. It is used as a tool of surveillance in the postoperative period. The levels of serum CEA and calcitonin and their doubling time is a useful guide in the detection of early recurrence or distant metastasis. Imaging modality useful for diagnosis is USG in a majority of patients. Thus, the initial diagnosis and preoperative assessment of medullary thyroid carcinoma is similar to other forms of thyroid cancer but further management of disease differs significantly form other forms of differentiated thyroid carcinoma or even anaplastic carcinoma. Prognosis however differs according to age, gender, presence or absence of lymph node metastasis at presentation, metastatic disease at presentation and levels of biochemical markers.

Use of Free Anterolateral Thigh Flap in Reconstruction of Soft Tissue Defects in Orthopedic Oncology: What are the Outcomes?

INTRODUCTION: Soft tissue defects due to trauma with crush injuries and post-tumor excision are large in size. Free anterolateral flap provides a stable and durable coverage of soft tissue defects and leads to good functional outcomes. MATERIALS AND METHODS: Between January 2017 and January 2019, eight males and six female patients with soft tissue defects were operated upon using a free anterolateral thigh flaps. The defects in ten patients were due to post-tumor extirpation and in four patients due to wound breakdown following post-tumor extirpation. RESULTS: The average flap dimension was 14 cm × 12 cm. The mean follow-up was 11 months (4-28 months). All the flaps survived well except in one patient who with an upper limb defect, had flap necrosis owing to which patient needed to undergo abdominal flap coverage. Two patients with sarcoma developed local recurrence and had to undergo above­knee amputation. CONCLUSION: The method of reconstruction depends on the size of defect and area to be covered and need of post-surgery mobilization and need for radiotherapy. The free anterolateral thigh flap has varied uses in orthopedics with very good extent of coverage and provides very potent coverage of neurovascular structures, bones, tendons, and implants.

Clinical and oncological outcomes of surgery in Anorectal melanoma in Asian population: A 15 year analysis at a tertiary cancer institute.

INTRODUCTION: Anorectal malignant melanoma (ARMM) is an aggressive malignancy with dismal prognosis and a 5-year survival rate less than 20% in most of the previous studies. The ideal surgical treatment has still remained controversial. This retrospective study aims at analysing the outcome in patients with ARMM treated with curative surgical resection. PATIENTS AND METHODS: This is a retrospective study of 38 patients of stage I anorectal malignant melanoma treated with curative surgical resection at our tertiary cancer institute. RESULTS: WLE (Wide Local Excision) was carried out in 12 patients and APR (abdominoperineal resection) was done in 26 patients. The median overall survival of the entire group in this study was 20 months. Although the median overall survival of WLE patients was higher than those with APR (37 months versus 16 months, respectively), this was not a statistically significant event (P=0.317). The 1-, 2-, 3-, 5-year survival rates were similar with both APR and WLE with no significant difference in the 5-year survival rate (P=0.816); overall 5-year survival rate of just 13%. There were 3 long-term survivors in this study group who survived for more than 10 years. CONCLUSION: Most patients ultimately succumb to the disease regardless of the management. Both APR and WLE have significant roles in the management depending on the subset of patients selected. Local treatment should be preferred wherever possible. Abdominoperineal resection should be offered in nodal disease or in a recurrent setting.

Coronavirus disease (COVID-19): A systematic review and meta-analysis to evaluate the impact of various comorbidities on serious events.

BACKGROUND AND AIMS: Currently there is limited knowledge on medical comorbidities and COVID-19; we conducted a systematic review and meta-analysis to evaluate the impact of various morbidities on serious events in COVID 19. METHODS: PubMed, Cochrane Central Register of Clinical Trials were searched on April 28, 2020, to extract published articles that reported the outcomes of COVID-19 patients. The search terms were "coronavirus" and "clinical characteristics". ICU admission, mechanical ventilation, ARDS, Pneumonia, death was considered serious events. The comorbidities assessed in the study were Hypertension (HTN), Diabetes mellitus (DM), Cardiovascular diseases (CVD), Chronic obstructive pulmonary disease (COPD) and Chronic Kidney disease (CKD). Subsequently, comparisons between comorbidity patient group and the non-comorbidity patient groups, in terms of serious events were made using the pooled estimates of odd's ratio (OR) RESULTS: We identified 688 published results and 16 studies with 3994 patients were included in the systematic review. Serious events were seen in 526(13.16%) patients. Presence of hypertension with OR 2.95, diabetes mellitus with OR 3.07, Cardio vascular disease with OR 4.58, COPD with OR 6.66 and Chronic kidney disease with OR 5.32 had significant association in patients with COVID 19 on having serious events. Presence of diabetes mellitus (OR 2.78)) had a significant impact on death in COVID 19 patients with a p-value 0.004. CONCLUSIONS: Presence of medical comorbidities in COVID-19 leads to higher risk of developing serious events i.e. ICU admission, mechanical intubation and mortality. The presence of Diabetes mellitus has a significant impact on mortality rate in COVID-19 patients.
