RESUMEN

INTRODUCTION: A significant proportion of breast cancer cases are hereditary and are potentially preventable. However, adoption of the preventive measures remains a significant challenge, particularly because of to lack of knowledge and awareness in low- to middle-income countries. METHODS: This prospective study conducted at a high-volume tertiary care cancer center in North India to assess the knowledge, awareness, and attitudes of female breast cancer patients and impact of a brief educational intervention. The study involved three phases: pre-interventional assessment, educational intervention, and post-interventional assessment utilizing a structured questionnaire. RESULTS: The study involved 300 newly diagnosed breast cancer patients; 16.7% were familial. At the outset, 87.0% patients had low knowledge of risk factors, 90.3% about screening, and 32.7% about treatment. Awareness levels were low: 13.7% aware of familial risk and 2.7% of breast cancer genes. Affordability of genetic testing was low (15.2%), and interest in testing for self and family members was limited (32.0% and 26.3%). Following educational intervention, a significant positive percentage change was noticed in knowledge (risk factors: 12.8%, screening: 36.2%, treatment: 82%), awareness (familial risk: 66.7%, BRCA gene: 12.3%), and attitude (testing for self: 17.8%, family: 19.5%). CONCLUSIONS: This study highlights the significant knowledge gaps among breast cancer patients regarding genetics. The educational intervention led to notable improvements in knowledge, awareness, and attitudes, underscoring the importance of tailored patient education in breast cancer care.

RESUMEN

BACKGROUND: Chest wall tumors are a heterogeneous group of tumors that are managed by surgeons from diverse specialties. Due to their rarity, there is no consensus on their diagnosis and management. MATERIALS: This retrospective, descriptive analysis includes patients with malignant chest wall tumors undergoing chest wall resection. Tumors were classified as primary, secondary, and metastatic tumors. The analysis includes clinicopathological characteristics, resection-reconstruction profile, and relapse patterns. RESULTS: A total of 181 patients underwent chest wall resection between 1999 and 2020. In primary tumors (69%), the majority were soft tissue tumors (59%). In secondary tumors, the majority were from the breast (45%) and lung (42%). Twenty-five percent of patients received neoadjuvant chemotherapy, and 98% of patients underwent R0 resection. Soft tissue, skeletal + soft tissue, and extended resections were performed in 45%, 70%, and 28% of patients, respectively. The majority of patients (60%) underwent rib resections, and a median of 3.5 ribs were resected. The mean defect size was 24 cm2. Soft tissue reconstruction was performed in 40% of patients, mostly with latissimus dorsi flaps. Rigid reconstruction was performed in 57% of patients, and 18% underwent mesh-bone cement sandwich technique reconstruction. Adjuvant radiotherapy and chemotherapy were given to 29% and 39% of patients, respectively. CONCLUSIONS: This is one of the largest single-institutional experiences on malignant chest wall tumors. The results highlight varied tumor spectra and multimodality approaches for optimal functional and survival outcomes. In limited resource setting, surgery, including reconstructive expertise, is very crucial.

RESUMEN

AIM: The objective is to evaluate the effect of intravenous (i.v.) administration of bisphosphonate (zoledronic acid) therapy on the jaw bone density and incidence of any other bony patholog. SETTINGS AND DESIGN: Observational - prospective study. MATERIALS AND METHODS: A total of 57 patients having a history of bony metastasis (excluding the jaw bone) were enrolled following the inclusion/exclusion criteria. Each patient received six doses of 4 mg i.v. bisphosphonate once a month. Multidetector computed tomography (MDCT) of jawbones for each patient was performed before the start of therapy (baseline) and subsequently at 6 and 12 months. Bone density was assessed at 24 predetermined sites (8 sites in maxilla and 16 sites in mandible) and any pathological change in either of the jaw bones was noted. STATISTICAL ANALYSIS USED: Shapiro-Wilk test ,Pearson's Chisquare test and repeated measures analysis of variance. RESULTS: The result showed no statistically significant increase in mean bone density over a period of 1 year in maxilla and mandible. However, a significant increase in bone density was observed from 6 months to 1 year in mandibular anterior cancellous bone. The detailed observation of each MDCT scan showed no pathological change in either of the jaw bones during the study period. CONCLUSION: The administration (i.v.) of six doses of 4 mg bisphosphonate did not lead to a significant change in bone density over a period of 1 year.

RESUMEN

Malignant peripheral nerve sheath tumour (MPNST) is a rare variety of soft tissue sarcoma that originates from Schwann cells or pluripotent cells of neural crest origin. They have historically been difficult tumours to diagnose and treat. Surgery is the mainstay of treatment with a goal to achieve negative margins. Despite aggressive surgery and adjuvant therapy, the prognosis of patients with MPNST remains poor. MPNST arising from penis is a very rare entity; thus, it presents a diagnostic and therapeutic challenge. We present a case of penile MPNST in a 38-year-old man in the absence of neurofibromatosis treated with surgery followed by post-operative radiotherapy to a dose of 60 Gray in 30 fractions and adjuvant chemotherapy with ifosfamide and adriamycin.

RESUMEN

BACKGROUND: Data on extraosseous Ewing sarcoma (EES) with uniform chemotherapy protocol are minimal. We aimed to examine this aspect in our patients, identify prognostic factors and compare the same with osseous Ewing sarcoma. PROCEDURES: A single institutional data review of patients with EES treated between June 2003 and November 2011 with uniform chemotherapy and evaluated on intent-to-treat analysis was done. RESULTS: Of 374 patients with Ewing sarcoma, 60 (16%) were EES with median age 16 years; 20 (33%) had metastases. After median follow-up of 25 months (range: 1.7-104.4), 5-year event free survival (EFS), OS, and local-control-rate were 47.1 ± 7.9%, 61.6 ± 7.8%, and 77.9 ± 8.6%, respectively for entire EES cohort. In multivariate analysis, hemoglobin ≤ 10 g/dl (P = 0.03), and white blood cell count (WBC) >11 × 10(9) /L (P = 0.009) predicted inferior EFS for the entire EES cohort. Low hemoglobin (P = 0.05) and high LDH (P = 0.01) predicted inferior OS for the entire EES cohort on multivariate analysis. As compared to the cohort of skeletal primary (n = 314), higher proportion of patients underwent surgery in the cohort of EES (P = .003); EFS (P = 0.004) and OS (P = 0.08) were superior for patients with EES than patients with skeletal Ewing sarcoma. CONCLUSION: These data of EES suggests that low hemoglobin and high WBC count adversely affect EFS. Overall outcome was significantly better for EES than skeletal primary tumors.

RESUMEN

BACKGROUND & OBJECTIVES: Staging of cervical carcinoma is done clinically using International Federation of Obstetrics and Gynecology (FIGO) guidelines. It is based on physical examination findings and also includes results of biopsy, endoscopy and conventional radiological tests like chest radiograph, intravenous urography and barium enema. These conventional radiological investigations have largely been replaced by computed tomography (CT) and magnetic resonance imaging (MRI) at present. FIGO staging system does not consider CT and MRI mandatory; however, use of these modalities are encouraged. This prospective study was conducted to determine the role of CT in staging work up in women diagnosed with cervical carcinoma. METHODS: Fifty three women diagnosed with cervical carcinoma were evaluated with contrast enhanced CT scan of abdomen and pelvis. CT scan images were especially evaluated to determine tumour size, invasion of parmetrium, pelvic walls, rectum, urinary bladder and ureters, pelvic or retroperitoneal lymphadenopathy and distant metastases. CT findings were associated with clinical findings and staging, including findings from cystoscopy and sigmoidoscopy. RESULTS: There was a poor agreement between clinical and CT staging of cervical carcinoma. Primary tumour was demonstrated on CT in 36 (70%) of 53 patients. CT underestimated the parametrial, vaginal and pelvic wall invasion when compared with physical examination. CT overestimated the urinary bladder and rectal invasion when compared with cysto-sigmoidoscopy, however, CT had 100 per cent negative predictive value (NPV) to exclude bladder and rectal involvement. CT detection of lymph node enlargement and lung metastases influenced the management. INTERPRETATION & CONCLUSIONS: Our findings show that CT scan does not reliably correlate with clinical FIGO staging of cervical cancer. However, it can detect urinary obstruction as well as nodal or distant metastases and thus improves the clinical FIGO staging.

RESUMEN

The ecologically friendly properties, low-cost, and readily available titanium dioxide (TiO2) materials have made them a subject of considerable interest for numerous promising applications. Anatase TiO2 nanoparticles were synthesized in the current study through the utilization of a hibiscus leaf extract and the advent of TiO2-doped g-C3N4(TiCN) nanocomposites (varying 0.5 mM, 1.0 mM, 1.5 mM, and 2.0 mM) by thermal polymerization. Here, the proposed study utilized multiple analytical techniques, including UV-Vis spectroscopy, a diffraction pattern (XRD), SEM coupled with EDX analysis, TGA, and EPR, to characterize the as-prepared TiO2 nanoparticles and TiCN nanocomposites. BET analysis the adsorption-desorption isotherms of the TiCN(1.5 mM) nanocomposite, the surface area of the prepared nanocomposite is 112.287 m2/g, and the pore size is 7.056 nm. The XPS spectra support the development of the TiCN(1.5 mM) nanocomposite by demonstrating the presence of C and N elements in the nanocomposite in addition to TiO2. HRTEM images where the formation of stacked that indicates a planar, wrinkled graphitic-like structure is clearly visible. The TiCN (1.5 mM) specimen exhibited enhanced morphology, enhanced surface area, greater capacity to take in visible light, and lowered band gap when compared to g-C3N4 following z-scheme heterojunction. The sample denoted as TiCN (1.5 mM) exhibited superior performance in terms of adsorption and photocatalytic activity using rhodamine B and Bisphenol A. Furthermore, the TiCN (1.5 mM) composite exhibited satisfactory stability over four cyclic runs, indicating its potential application in minimizing the impact of organic wastewater contaminants when compared to g-C3N4.

RESUMEN

BACKGROUND: Adult soft tissue sarcomas (STS) are rare and diverse. Current management is based on limited literature from the West. Therefore, data from different geographical regions is required, including the low-middle-income countries. This is our experience managing adult sarcomas in the tertiary cancer center of North India. MATERIALS AND METHODS: This is a retrospective analysis of the structured sarcoma database of patients treated in the surgical oncology department between 1992 and 2020. The descriptive analysis includes demography, site distribution, diagnosis, histopathology variations, prior surgical interventions, and stage. RESULTS: A total of 1106 soft tissue sarcoma patients were treated in three decades. Age distribution was 13%, 43%, 31%, and 11% in <20, 21-40, and 41-60 and >60 years, respectively. The male-to-female ratio was 1.73. The anatomical distribution was 17%, 42%, 23%, 7%, 7%, and 3% in upper extremity, lower extremity, trunk, retroperitoneum, head and neck, and viscera, respectively. Overall, 49% of patients had undergone prior suboptimal surgeries at community hospitals. Common histology subtypes were synovial sarcoma (18%), undifferentiated pleomorphic sarcoma (UPS) (13%), dermatofibrosarcoma protuberans (12%), and liposarcoma (9%). A pathological discordance of 13% was identified between the initial and the final histologies. Overall, 61% of tumors were high-grade. Memorial Sloan Kettering Stages II and III were present in 33% and 35% of patients, respectively. CONCLUSIONS: This is one of the largest single institutional experiences of STS from the Asian population. Mostly young adults were affected with male preponderance. The lower extremity and trunk were common subsites. Frequent histologies were synovial sarcoma and UPS. A high rate of suboptimal surgical intervention at the community level and pathological discordance was noted. This study highlights the need to establish prospective structured databases for capturing quality information related to rare malignancies and providing insights for future research.

RESUMEN

Introduction: Breast cancer is the most common cancer among Indian females. There is limited data on germline profiling of breast cancer patients from India. Objective: The objective of the current study was to analyse the frequency and spectrum of germline variant profiles and clinicopathological characteristics of breast cancer patients referred to our Familial Cancer Clinic (FCC). Materials and methods: It is a single-centre audit of patients with a confirmed diagnosis of breast carcinoma referred to our FCC from January 2017 to 2020. All patients underwent pretest counselling. Genetic testing was done by multigene panel testing by next-generation sequencing along with reflex multiplication ligation-dependent probe amplification for BRCA1 and 2. The variants were classified based on American College of Medical Genetics guidelines. Demographic and clinicopathological details were extracted from the case record files. Results: One hundred and fifty-five patients were referred to the FCC and underwent pretest counselling. A total of 99 (63.9%) patients underwent genetic testing. Among them, 62 patients (62/99 = 62.6%) had a germline variant. A pathogenic/likely pathogenic (P/LP) germline variant was identified in 41 (41.4%) of the patients who underwent testing. Additional variants of unknown significance (VUS) were identified in seven patients who also carried a P/LP variant. VUS alone was detected in 21 patients (21/99 = 21.2%). Among the P/LP pathogenic variants (PV), BRCA 1 PV were seen in 27 patients (65.8%), BRCA 2 variants in 7 patients (17.1%), ATM variants in 3 patients (7.3%) and RAD51, TP53, CHEK2 and HMMR in 1 patient each. Variants were significantly more common in patients with a family history (FH) of malignancy than those without FH (58.5% versus 29.5%; p = 0.013). Age and triple-negative histology were not found to be significantly associated with the occurrence of P/LP PVs. Conclusion: We report a 41% P/LP variant rate in our selected cohort of breast cancer patients, with variants in BRCA constituting 83% and non-BRCA gene variants constituting 17%.

RESUMEN

AIMS: Synovial sarcoma is a rare but aggressive variant of soft-tissue sarcoma. Literature is sparse and reported mostly from the West. We analysed the clinical profiles and prognostic factors of extremity synovial sarcoma patients in order to study their clinical journey. MATERIALS AND METHODS: This was a retrospective analysis. All patients with extremity synovial sarcoma treated between 1992 and 2020 were included. Patients with metastases at presentation were excluded. A descriptive analysis of demographic and clinicopathological features of patients undergoing limb salvage surgery (LSS) or amputation was carried out. Overall survival and disease-free survival were calculated for the entire cohort as well as for the LSS and amputation groups. Factors prognostic for survival were identified. RESULTS: In total, 157 patients had localised extremity synovial sarcoma. Predominantly, young adults (median 31 years) and males (61%) were affected. Over 70% of patients presented after recurrence or unplanned surgeries. Sixty-seven per cent of tumours were >5 cm, 69% were deep and 23% involved bone. The limb salvage rate was 64%. In the LSS group, adjuvant radiotherapy and chemotherapy were given to 72% and 68% of patients, respectively. In the amputation group, 72% of patients received adjuvant chemotherapy. In a median follow-up of 59 months, 39.4% of patients had recurrences, the majority (61.2%) were systemic. Five-year overall survival and disease-free survival were 53.4% and 49.8%, respectively. Overall survival was 63.9% and 29.7% in the LSS and amputation groups, respectively. On multivariate analysis, tumour size, depth, omission of radiotherapy and bone invasion were found to be the adverse prognostic factors. CONCLUSION: This is one of the largest studies on extremity synovial sarcoma. Mostly males and young adults were affected. The limb salvage rate was 64%, despite most being referred after unplanned surgery. Almost 70% of patients received radiotherapy and chemotherapy. Overall survival was inferior in the amputation group. Tumour size >5 cm, depth and bone invasion were negative, whereas adjuvant radiotherapy was a positive prognostic factor for survival. Chemotherapy had no impact on survival.

RESUMEN

Data on prognostic factors in pelvic PNET are minimal. We analyzed patients with pelvic PNET treated between June 2003 and November 2011 for prognostic factors. Forty-eight (13%) of 374 patients with PNET were pelvic PNET with median age 14.5 years (range: 5-33); 31 (65%) had metastases. After median follow-up of 20.4 months (range: 1.3-64.9), 3-year EFS, OS, and local-control-rate were 13.5 ± 5.5%, 15.4 ± 9%, and 41.3 ± 14.9%, respectively. Hypoalbuminemia (≤3.4 g/dl) predicted inferior EFS and OS for both entire cohort and metastatic group. All patients with hypoalbuminemia (n = 10) had low BMI as compared to 23/38 without hypoalbuminemia (P = 0.02).

RESUMEN

BACKGROUND: Neoadjuvant chemotherapy (NACT) with human epidermal growth factor receptor 2 (HER2) blockade is the preferred approach for treating early and locally advanced HER2-positive breast cancer. There is a lack of robust data comparing pathological complete response (pCR) and survival outcomes in anthracycline-free and anthracycline-containing regimens with single HER2-targeted therapy. OBJECTIVES: The present study retrospectively evaluated pCR between two groups: Single HER2-targeted therapy with and without anthracycline. METHODS: A total of 215 HER2-positive female breast cancer patients were analyzed who received eitheranthracycline-containing EC-TH (epirubicin and cyclophosphamide, followed by docetaxel and trastuzumab)oranthracycline-free TCH [docetaxel, carboplatin and trastuzumab]. Univariate and multivariate analyses identified prognostic factors for survival and pCR.Kaplan Meier survival curvesdetermined disease-free survival(DFS) and overall survival (OS). RESULTS: Baseline characteristics were comparable in both treatment groups. The pCR rate was 30.8% in the anthracycline-containing EC-TH group and 40.9% in the anthracycline-free TCH group; p = 0.140. Disease-free survival at 3 years (65.8% vs. 58.4%) and 5 years (49.2% vs. 55.2%) was similar between EC-TH and TCH groups, respectively (log-rank p = 0.550). Three-year (95.5% vs. 92.5%) and five-year (84.4% vs. 80.8%) OSwere also comparable between both groups (log-rank p = 0.485). The anthracycline-containing EC-TH group had a higher incidence of febrile neutropenia (6.4%. vs. 3.6%) and cardiac adverse events (7.7% vs. 4.4%) than the anthracycline-free TCH group. CONCLUSION: Neoadjuvant anthracycline-free chemotherapy has similar pCR and survival outcomeswith favourable cardiac and non-cardiac adverse effect profiles compared with anthracycline-containing chemotherapy.

RESUMEN

There is paucity of literature regarding the demography, histopathology, management, and outcomes of bilateral breast cancer (BBC). We present our experience of treating 127 BBC with multimodality management. An audit of prospectively maintained computerized breast cancer database of the department of surgical oncology at a tertiary care center was performed. Demography, clinical profile, molecular sub-types, treatment patterns, and outcomes were analyzed. A total 127 patients presented with BBC between 1992 and 2019. Ninety-four had metachronous (MBBC) and 33 had synchronous breast cancer (SBBC). Most contralateral breast cancer (CBC) patients had early-stage breast cancer in comparison to the index side cancer (37% vs 32%). Ninety-four patients underwent bilateral mastectomy and only 18 patients underwent bilateral breast conservation. Seventy-one patients undergoing BCS and surgery for LABC were given postoperative radiotherapy. All patients received adjuvant chemo- and/or hormonal therapy both for index and CBC based on the stage and hormone receptor status. Thirty-three percent of patients had either locoregional or distant relapse. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) of the entire cohort were 86.6% and 68.4% respectively. There was no difference in the OS and DFS between SBBC and MBBC. The incidence of BBC is expected to increase with effective diagnostic and therapeutic interventions and improving survival. Patients require individualized treatment planning in a multidisciplinary treatment setting.

RESUMEN

Conservative management of metachronous second primary carcinoma of head and neck is preferred in order to preserve form and function. The purpose of the case report is to describe the treatment of metachronous second primary carcinoma of soft palate by high-dose-rate, remote, afterload brachytherapy. The brachytherapy was done in remote settings by afterloading Iridium 192 isotope carried through a custom fabricated surface mold. The mold enabled good adaptation, stability, and repeatable positioning of the radiation source at each treatment session of fractionated brachytherapy offering consistent dosimetric advantage through a single dosimetry calculation. Collaborative efforts of radiation oncologist and prosthodontist ensured conservative treatment in outpatient set up with minimal adverse effects.

RESUMEN

CONTEXT: Vulvar carcinoma accounts for 3%-5% of gynecologic malignancies. The past three decades has observed changes in the trends of clinical characteristics and treatment modalities used in managing this disease. AIMS: The aim of the present study is to analyze the clinic-pathological characteristics and survival of women with squamous cell carcinoma vulva who underwent primary surgical management. SETTINGS AND DESIGN: This was a retrospective observational study. SUBJECTS AND METHODS: Case records of 30 consecutive patients with squamous cell carcinoma of vulva during the period of 2010-2016 were retrospectively reviewed and their clinical profile, treatment details, complications, and survival were analyzed. STATISTICAL ANALYSIS USED: Kaplan-Meier survival analysis, followed by logrank test, was used for survival outcome, and Cox proportional hazard model was used to assess significant risk factors. RESULTS: The mean age of patients was 58 ± 12.9 years. The most common symptom was growth over vulva (73.3%), itching (63.3%), and nonhealing vulval ulcer (26.6%). The most common site for disease was labia majora. The surgical treatments ranged from wide local excision to radical vulvectomy. Postoperative adjuvant therapy was required for 16 patients. The median (95% confidence interval [CI]) overall survival was 27 (21.7-32.2) months. Five-year survival probability for early-stage disease (I + II) was 49% (95% CI: 12.9, 78.4) and for advanced disease (III + IV) was 24.8% (95% CI: 4.8, 42.6). Lymph node-positive status was found to have a significant impact on survival (hazard ratio of 4.9 [95% CI: 1.15-21.02, P = 0.02]). CONCLUSIONS: Despite advances in detection and management modalities, the survival for vulval malignancies has not improved.

RESUMEN

Locally advanced breast cancer (LABC) patients require an accurate staging of the disease to rule out distant metastases. Various imaging investigations are used to stage LABC patients. The present study is a prospective comparison of conventional imaging (CI) with fusion positron-emission tomography and computed tomography (PET-CT) scans in the staging of LABC patients. Seventy-three consecutive LABC patients presenting to the breast cancer clinic of the tertiary care cancer institute were included in the study. All patients underwent contrast-enhanced computed tomography, Tv99m bone scintigraphy, and fusion PET-CT. Histology of the metastatic site was confirmed wherever possible. The disparity between the two imaging findings was compared. Doubtful lesions were observed clinically for at least 2 years to confirm their nature. PET-CT detected a higher number of lymph nodes in the axilla, internal mammary, and supraclavicular region as compared to CI. PET-CT upstaged 36.98% and downstaged 5.4% of the patients respectively leading to a change in the management in 30.13% of the patients. Sensitivity, specificity, positive predictive value, and negative predictive value of CI and PET-CT were 71.87%, 87.80%, 82.14%, and 80%, and 90.90%, 90%, 88.23%, and 92.30% respectively. PET-CT was more accurate in staging the LABC patients as compared to CI. PET-CT is more accurate then contrast-enhanced CT and bone scintigraphy for staging locally advanced breast carcinoma patients. It can replace multiple organ-directed imaging in staging breast cancer. It can provide accurate staging of the disease so that patients can be prognosticated and can be directed to the most appropriate treatment plans.

RESUMEN

OBJECTIVE: The COVID-19 pandemic has dramatically affected healthcare services around Asia. The Asian National Cancer Centres Alliance and the Asia-Pacific Organisation for Cancer Prevention collaborated to assess the mid- and long- term impact of COVID-19 to cancer care in Asia. METHODS: The two entities organised a combined symposium and post-meeting interactions among representatives of major cancer centres from seventeen Asian countries to outlining major challenges and countermeasures. RESULTS: Participating stakeholders distilled five big questions. 1) "Will there be an explosion of late-stage cancers after the pandemic?" To address and recover from perceived delayed prevention, screening, treatment and care challenges, collaboration of key stakeholders in the region and alignment in cancer care management, policy intervention and cancer registry initiatives would be of essential value. 2) "Operations and Finance" The pandemic has resulted in significant material and financial casualties. Flagged acute challenges (shortages of supplies, imposition of lockdown) as well as longer-standing reduction of financial revenue, manpower, international collaboration, and training should also be addressed. 3) "Will telemedicine and technological innovations revolutionize cancer care?" Deploying and implementing telemedicine such as teleconsultation and virtual tumour boards were considered invaluable. These innovations could become a new regular practice, leading to expansion of tele-collaboration through collaboration of institutions in the region. 4) "Will virtual conferences continue after the pandemic?" Virtual conferences during the pandemic have opened new doors for knowledge sharing, especially for representatives of low- and middle-income countries in the region, while saving time and costs of travel. 5) "How do we prepare for the next pandemic or international emergency?" Roadmaps for action to improve access to appropriate patient care and research were identified and scrutinised. CONCLUSION: Through addressing these five big questions, focused collaboration among members and with international organisations such as City Cancer Challenge will allow enhanced preparedness for future international emergencies.
