Abstract
Purpose Cessation of elective surgery during COVID-19 was partly driven by concern for consumption of hospital resources required by critically ill patients. We aim to determine the extent of resource utilization by elective outpatient surgery to assist in ensuring future resource conservation decisions are data driven. Methods The study utilized a retrospective cohort gathered from the American College of Surgeons National Surgical Quality Improvement Program database. Participants were adult patients who underwent elective or non-elective surgery between 2017 and 2018. Outcomes included patient characteristics and post-operative outcomes for elective and non-elective surgeries. Post-operative outcomes were used as a surrogate for the consumption of hospital resources. Results A total of 1,558,938 (79.8%) elective and 393,339 (20.2%) non-elective surgeries were identified. Elective surgery patients were more likely to be outpatient status, have an ASA class < 3, and exhibited lower rates of prolonged ventilation, 30-day reoperation, and 30-day readmissions, and averaged 5 days less of inpatient stay. Elective outpatient surgery (vs. elective inpatient surgery) averaged shorter operative times and exhibited lower rates of readmissions (2.1% vs. 5.5%; p < 0.001), reoperations (1.1% vs. 2.8%; p < 0.001), prolonged ventilation (0.0% vs. 0.3%; p < 0.001), and 30-day mortality (0.1% vs. 0.5%; p < 0.001) and accounted for 30.2% of the overall relative value units ($339,815,038). Conclusion We evaluated utilization of hospital resources by patients undergoing elective outpatient surgery by identifying surgeries performed in 2017–2018 then stratifying them by outpatient status. Elective outpatient surgeries consumed negligible amounts of hospital resources and should not be considered a threat to resources in the setting of high demand by critically ill COVID-19 patients.

Abstract
Background: There is a high incidence of hand and wrist injuries in athletes participating in collegiate sports, but there is little information published characterizing them. Purpose: To characterize hand and wrist injuries in collegiate athletes using a large national database. Study Design: Descriptive epidemiology study. Methods: This retrospective cross-sectional analysis was designed using data from the National Collegiate Athletic Association (NCAA) Injury Surveillance Program database to identify hand and wrist injuries (exclusive of any radial or ulnar fractures) in male and female collegiate athletes participating in NCAA Division I, II, and III sports from 2004 to 2015. Descriptive analyses were performed on stratified data to examine the associations between these injuries and sport, event type, and sex. Results: Men’s ice hockey (8.25 per 10,000 athlete-exposures [AEs]) and women's ice hockey (8.21 per 10,000 AEs) had the highest rate of hand and wrist injuries in all exposures. In every sport except women’s gymnastics (P = .107), injuries were more commonly sustained during competition rather than during practice. Ligamentous injury to the phalynx was the most commonly sustained injury overall (1.416 per 10,000 AEs), and a metacarpal fracture was the most commonly sustained hand or wrist fracture (0.507 per 10,000 AEs). Injuries sustained during men’s wrestling (14.08 days) and women’s gymnastics (10.39 days) incurred the most time lost from sport. Surgery for hand and wrist injuries was most commonly required for men’s football (0.413 per 10,000 AEs) and women’s field hockey (0.404 per 10,000 AEs). Conclusion: Hand and wrist injuries were common among collegiate athletes. Male athletes experienced injuries with more frequency and severity. Injuries occurred more commonly during competition. While the majority of injuries were minor and did not require surgery, certain sports conferred a much higher risk of significant injuries requiring a surgical intervention.

Evolving multidisciplinary treatment of squamous cell carcinoma of the head and neck in India ✰. Cancer Treat Res Commun 2020; 26:100269.

Abstract
In this article, we highlight the evolution of a multimodal approach in the overall management of squamous cell carcinoma of the head and neck (SCCHN) in India; present advances in technology (newer surgical techniques), novel medical and radiotherapy (RT) approaches; review their roles for an integrated approach for treating SCCHN and discuss the current role of immunotherapy in SCCHN. For locally advanced (LA) SCCHN, the multidisciplinary approach includes surgery followed by RT, with or without chemotherapy (CT) or concurrent chemoradiotherapy. Improved surgical techniques of reconstruction and voice-preservation are being implemented. Advanced forms of high-precision conformal techniques like intensity-modulated radiotherapy are used to deliver highly conformal doses to tumors, sparing the surrounding normal tissue. Compared with RT alone, novel CT regimens and targeted therapeutic agents have the potential to improve locoregional control and survival and reduce treatment-induced toxicities. Several clinical trials have demonstrated efficacy, safety, and quality of life benefits of adding cetuximab to RT regimens in LASCCHN. Studies have also suggested a cetuximab-related laryngeal preservation benefit. At progression, platinum-based CT combined with cetuximab (a monoclonal anti-epidermal growth factor receptor antibody) is the only validated option available as the first-line therapy. Thus, an integrated multidisciplinary approach plays a key role in maximizing patient outcomes, reduction in treatment related morbidities that consequently impact quality of life of survivors.

Abstract
Background An increasing number of patients undergo contralateral prophylactic mastectomy (CPM) for unilateral breast cancer. However, the benefit of CPM has not been quantified in the setting of contemporary breast cancer therapy. Methods We performed an analysis of 180 068 patients in the Surveillance, Epidemiology, and End Results (SEER) database, diagnosed with unilateral ductal breast carcinoma between 1998 and 2013 and treated with unilateral mastectomy (UM) or CPM. UM was performed in 146 213 patients (81.2%); CPM was performed in 33 855 patients (19.8%). Primary outcome of interest was cumulative incidence of a second primary breast cancer in the ipsilateral or contralateral breast greater than 3 months after initial diagnosis. Cumulative incidence analysis was based on a Cox proportional model to generate curves of second primary breast cancer in any breast, ipsilateral breast only, or contralateral breast only. Results Patients who underwent CPM had a significantly reduced incidence of second primary breast cancer 10 and 15 years after surgery (CPM 0.93% [0.73%, 1.12%] vs UM 4.44% [4.28%, 4.60%]). Patients who underwent CPM had significantly lower adjusted hazard of second primary breast cancer when compared with UM (HR 0.38 vs 1.0, P < .0001). Conclusions CPM offers some protection from a second primary breast cancer, attributable to a reduced incidence in the contralateral breast. These findings provide additional information to providers and patients as they make decisions regarding surgical management. They should also be interpreted in the context of the absolute incidence of second primary breast cancer after UM and previous literature demonstrating no survival benefit.

Abstract
BACKGROUND Traditionally, surgical quality outcomes are assessed using a 30-day postoperative window. For breast cancer patients undergoing free tissue transfer for breast reconstruction, we sought to describe the distribution of and specific risk factors for early and late readmissions within a 0- to 90-day postoperative period. PATIENTS AND METHODS The Nationwide Readmissions Database was used to conduct a retrospective cohort study. Breast cancer patients undergoing free tissue transfer for breast reconstruction were identified using International Classification of Diseases -9 diagnosis and procedure codes. Ninety-day readmissions related to infection or wound complications were identified. Univariable and multivariable logistic regression models were used to identify patient risk factors for readmissions that occurred early (0-30 days) and late (31-90 days) after their index procedure. RESULTS In the weighted sample, we identified approximately 7,305 free flap breast reconstructions and a surgical wound-related readmission rate of 4.3% (n = 312): 65.4% of the readmissions occurred early while 34.6% occurred late after surgery. The mean days to readmission was 26, and 75% of all readmissions occurred within the first 36 days after surgery. Variables independently associated with readmissions during the 0- to 90-day postoperative period included: history of chronic obstructive pulmonary disease (p = 0.036), hypertension (p = 0.03), obesity (p ≤ 0.001), and history of smoking (p = 0.004). The variables independently associated with the early readmission period were the same as those identified for the 0- to 90-day postoperative period. The variables independently associated with late readmissions were different: history of depression (p = 0.001) and history of smoking (p = 0.001). CONCLUSION The conventional 30-day hospital readmission rate classically used as a quality metric is overlooking a significant portion of admissions after free flap-based breast reconstruction. Different variables were found to be associated with readmission in the early versus late cohorts. Interventions targeting these variables could decrease readmissions and their associated costs.

Abstract
Purpose To ascertain the dosimetric performance of a new delivery system (the Halcyon system, H) equipped with dual-layer stacked multi-leaf collimator (MLC) for risk-adapted targets in cervix uteri cancer patients compared to another ring-based system in clinical operation (Helical Tomotherapy, HT). Methods Twenty patients were retrospectively included in a treatment planning study (10 with positive lymph nodes and 10 without). The dose prescription (45Gy to the primary tumour volume and a simultaneously integrated boost up to 55Gy for the positive patients) and the clinical planning objectives were defined consistently as recommended by an ongoing multicentric clinical trial. Halcyon plans were optimised for the volumetric modulated arc therapy. The plan comparison was performed employing the quantitative analysis of the dose-volume histograms. Results The coverage of the primary and nodal target volumes was comparable for both techniques and both subsets of patients. The primary planning target volume (PTV) receiving at least 95% of the prescription isodose ranged from 97.2 ± 1.1% (node-negative) to 99.1 ± 1.2% (node-positive) for H and from 96.5 ± 1.9% (node-negative) to 98.3 ± 0.9% (node-positive) for HT. The uncertainty is expressed at one standard deviation from the cohort of patient per each group. For the nodal clinical target volumes, the dose received by 98% of the planning target volume ranged 55.5 ± 0.1 to 56.0 ± 0.8Gy for H and HT, respectively. The only significant and potentially relevant differences were observed for the bowels. In this case, V40Gy resulted 226.3 ± 35.9 and 186.9 ± 115.9 cm3 for the node-positive and node-negative patients respectively for Halcyon. The corresponding findings for HT were: 258.9 ± 60.5 and 224.9 ± 102.2 cm3. On the contrary, V15Gy resulted 1279.7 ± 296.5 and 1557.2 ± 359.9 cm3 for HT and H respectively for node-positive and 1010.8 ± 320.9 versus 1203.8 ± 332.8 cm3 for node-negative. Conclusion This retrospective treatment planning study, based on the dose constraints derived from the Embrace II study protocol, suggested the essential equivalence between Halcyon based and Helical Tomotherapy based plans for the intensity-modulated rotational treatment of cervix uteri cancer. Different levels of sparing were observed for the bowels with H better protecting in the high-dose region and HT in the mid-low dose regions. The clinical impact of these differences should be further addressed.

Abstract
Oral cavity cancer (OCC) poses a global challenge that plagues both the Orient and the Occident, accounting for an estimated 350 000 new cases and 177 000 deaths in 2018. OCC is a major public health problem in the Indian subcontinent, where it ranks among the top three cancer types in both incidence and mortality. Major risk factors are the use of tobacco, betel quid and alcohol consumption. OCC is a heterogeneous group of multiple histologies that affects multiple subsites. The oral cavity includes the lips, buccal mucosa, teeth, gingiva, anterior two-thirds of the tongue, floor of the mouth and hard palate. OCC is defined as cancer of lips, mouth and tongue as defined by the International Classification of Diseases coding scheme. The epidemiology, aetio-pathogenesis and treatment philosophy are similar within this group. Although salivary gland malignancies, sarcomas, mucosal melanomas and lymphomas can also arise within the oral cavity, this review will focus on squamous cell cancer, which is the predominant histology in OCC. We review and contrast data from developing and developed countries. We also highlight the unique regional challenges that countries in the East face; citing India as an example, we elaborate on the opportunities and scope for improvement in the management of OCC.

Abstract
Epidermal downgrowth around percutaneous devices produce sinus tracts, which then accumulate bacteria becoming foci of infection. This mode to failure is epidermal-centric, and is accelerated by changes in the chemokines and cytokines of the underlying periprosthetic granulation tissue (GT). In order to more fully comprehend the mechanism of downgrowth, in this 28-day study, percutaneous devices were placed in 10 Zucker diabetic fatty rats; 5 animals were induced with diabetes mellitus II (DM II) prior to the surgery and 5 animals served as a healthy, nondiabetic cohort. At necropsy, periprosthetic tissues were harvested, and underwent histological and polymerase chain reaction (PCR) studies. After isolating GTs from the surrounding tissue and extracting ribonucleic acids, PCR array and quantitative-PCR (qPCR) analyses were carried-out. The PCR array for 84 key wound-healing associated genes showed a five-fold or greater change in 31 genes in the GTs of healthy animals compared to uninjured healthy typical skin tissues. Eighteen genes were overexpressed and these included epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR). Thirteen genes were underexpressed. When GTs of DM II animals were compared to healthy animals, there were 8 genes overexpressed and 25 genes underexpressed; under expressed genes included EGF and EGFR. The qPCR and immunohistochemistry data further validated these observations. Pathway analysis of genes up-regulated 15-fold or more indicated two, EGFR and interleukin-10, centric clustering effects. It was concluded that EGFR could be a key player in exacerbating the epidermal downgrowth, and might be an effective target for preventing downgrowth.

Abstract
BACKGROUND Bilateral mastectomy rates are increasing in the United States. The abdomen is the most common harvest site for autologous reconstruction. Nationwide data were examined to determine differences in hospital charges, length of stay (LOS), and early postoperative complications following immediate bilateral pedicled transverse rectus abdominis myocutaneous (pTRAM), free TRAM (fTRAM), deep inferior epigastric perforator (DIEP), and superficial inferior epigastric artery (SIEA) perforator flaps and were compared with unilateral reconstruction. METHODS Patients who underwent immediate bilateral breast reconstruction using a single method of abdominally based reconstruction were identified using the 2009 to 2014 Nationwide Inpatient Sample Database. Outcomes included total hospital charges, LOS, and immediate postoperative complications. RESULTS We identified 13,348 cases of bilateral mastectomy with a single type of immediate bilateral autologous flap reconstruction. The majority were bilateral DIEP flaps. Mean total cost for bilateral pTRAM, fTRAM, DIEP, and SIEA flaps was US $21,886.80, US $28,839.40, US $30,051.30, and US $33,784.90, respectively (p < 0.0001). Mean LOS for bilateral pTRAM, fTRAM, DIEP, and SIEA was 4.3, 4.9, 4.5, and 5.4 days, respectively (p = 0.0002), and hematoma rates were 1.93, 2.61, 3.68, and 16.59%, respectively, (p = 0.0001), whereas return to the operating room for vascular anastomosis revision was 0, 1.63, 1.99, and 19.07%, respectively (p < 0.0001). Cost is less for unilateral pTRAM, fTRAM, and DIEP flaps (p < 0.0001). LOS is shorter for unilateral fTRAM versus bilateral (p < 0.0001). No differences were appreciated between unilateral and bilateral hematoma and reoperation rates for any reconstruction (p > 0.1). CONCLUSION Immediate complication rates were higher in bilateral free flaps compared with bilateral pedicled flaps. pTRAM and fTRAM flap reconstructions are still performed frequently with acceptable immediate results without considering long-term morbidity, aesthetics, and abdominal muscle function. Bilateral SIEA free flaps were associated with significantly higher total cost, LOS, and complication rates compared with other groups. Complications were similar between unilateral and bilateral reconstruction procedures. While cost is significantly greater for bilateral procedures compared with unilateral pTRAM, fTRAM, and DIEP flaps, it is not doubled.

Abstract
AIMS To report the findings of an audit for radiotherapy errors from a low-middle-income country (LMICs) centre. This would serve as baseline data for radiotherapy error rates, their severity and causes, in such centres where modern error reporting and learning processes still do not exist. MATERIALS AND METHODS A planned cross-sectional weekly audit of electronic radiotherapy charts at the radiotherapy planning and delivery step for all patients treated with curative intent was conducted. Detailed analysis was carried out to determine the step of origin of error, time and contributing factors. They were graded as per indigenous institutional (TMC) radiotherapy error grading (TREG) system and the contributing factors identified were prioritised using the product of frequency, severity and ease of detection. RESULTS In total, 1005 consecutive radically treated patients' charts were audited, 67 radiotherapy errors affecting 60 patients, including 42 incidents and 25 near-misses were identified. Transcriptional errors (29%) were the most common type. Most errors occurred at the time of treatment planning (59.7%), with "plan information transfer to the radiation oncology information system" being the most frequently affected sub-step of the radiotherapy process (47.8%). More errors were noted at cobalt units (52/67; 77.6%) than at linear accelerators. Trend analysis showed an increased number of radiotherapy incidents on Fridays and near-misses on Mondays. Trend for increased radiotherapy errors noted in the evening over other shifts. On severity grading, most of the errors (54/60; 90%) were clinically insignificant (grade I/II). Inadequacies and non-adherence towards standard operating procedures, poor documentation and lack of continuing education were the three most prominent causes. CONCLUSION Preliminary data suggest a vulnerability of LMIC set-up to radiotherapy errors and emphasises the need for the development of longitudinal prospective processes, such as voluntary reporting and a continued education system, to ensure robust and comprehensive safe practises on par with centres in developed countries.

Abstract
BACKGROUND Breast reduction is one of the most common procedures performed by plastic surgeons. Despite good outcomes and high patient satisfaction, there are little national data on the predictors that lead to complications in this patient population. We accessed a national outcomes database to examine these factors. METHODS This is a retrospective study examining the National Surgical Quality Improvement Program database from 2006 to 2015. Patients who underwent primary breast reduction were identified. Patients who underwent any cancer-related procedures were excluded. We identified patient-related and procedure-related factors for analysis. Univariate and multivariate logistic regression analyses were used to identify independent predictors of complications. RESULTS In total, 16,812 individual cases were identified. The overall complication rate for the cohort was 6.2%, and the major complication rate was 3.0%. Diabetes, bleeding disorder, hypertension, obesity, smoking, steroid use, and prolonged operative time were associated with increased risk of complications (p < 0.05). Concurrent body contouring was a predictor of increased major complications; however, liposuction was not. CONCLUSIONS Common surgical risk factors are associated with complications in breast reduction surgery. Although liposuction is not an independent risk factor, concurrent body contouring is associated with increased complications. Surgeons should be aware of these associations when discussing breast reduction with patients.

Abstract
BACKGROUND The abdomen is the most common area from which tissue is harvested for autologous breast reconstruction. We sought to examine national data to determine the differences in total hospital charges, length of stay (LOS), and early postoperative complications following pedicled transverse rectus abdominis myocutaneous flap (pTRAM), free TRAM (fTRAM), deep-inferior epigastric perforator (DIEP), and superficial inferior epigastric artery perforator (SIEA) flaps. METHODS The 2009-2013 Nationwide Inpatient Sample Database was used to identify patients who underwent a unilateral mastectomy and only one type of abdominally based autologous flap (pTRAM, fTRAM, DIEP, and SIEA) during the same hospital admission. Outcomes of interest included total charges, LOS, and complications including revision of vascular anastomosis and hematoma. RESULTS A total of 3,310 cases were identified, corresponding to 15,991 abdominally based unilateral immediate breast reconstructions after standard weighting was applied; 5,079 (31.8%) were pTRAM flaps, 4,461 (27.9%) were fTRAM flaps, 6,206 (38.8%) were DIEP flaps, and 245 (1.5%) were SIEA flaps. The mean total charges for pTRAM, fTRAM, DIEP, and SIEA flaps were $17,765.5, $22,637.6, $25,814.6, and $26,605.2, respectively (p < 0.0001). The mean LOS for pTRAM, fTRAM, DIEP, and SIEA flaps were 96.5, 106.5, 106.7, and 108.9 hours, respectively (p = 0.002). The rates for return to the OR for the revision of a vascular anastomosis for pTRAM, fTRAM, DIEP, and SIEA were 0.0%, 1.72%, 2.66%, and 5.64%, respectively (p < 0.0001). CONCLUSIONS There is variation in the total charges, LOS, and early complications between pTRAM, fTRAM, DIEP, and SIEA flap-based breast reconstruction. fTRAM, DIEP, and SIEA flaps incur higher hospital total charges, have longer lengths of stay, and experience more immediate complications compared with pTRAM. Well-designed prospective trials are required to better understand the findings from this study with the inclusion of other critical outcomes such as patient satisfaction, aesthetic results, and long-term outcomes such as abdominal wall morbidity.

Abstract
BACKGROUND Fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has become a preferred imaging modality for the evaluation of solitary pulmonary nodule (SPN), particularly in the developed world. Since FDG can concentrate in infective/inflammatory lesions, the diagnostic utility of FDG-PET can be questioned, particularly in regions endemic for infectious decisions. AIM To evaluate the accuracy of FDG-PET/CT in evaluation of SPNs in a population endemic for infectious disease and to assess if regional variations have an impact on its effectiveness. MATERIALS AND METHODS All patients who underwent an FDG/PET-CT with a clinico-radiological diagnosis of SPN categorized as indeterminate were included. Based on a maximum standardized uptake values (SUVmax) cut-off of 2.5, lesions were classified as benign (<2.5) or malignant (>2.5) and compared with gold standard histopathology. The diagnostic accuracy of PET-CT to detect malignancy was calculated. On the basis of final histopathology, lesions were grouped as (a) malignant nodules (b) infective/granulomatous nodules with a specific diagnosis and (c) nonspecific inflammatory nodules. The SUVmaxbetween these groups was compared using nonparametric statistical tests. RESULTS A total of 191 patients (129 males, 62 females) with a median age of 64 years (range: 36-83) were included. Totally, 144 nodules (75.3%) were malignant and 47 were benign (24.7%). Adenocarcinoma (n = 84) was the most common malignancy. Tuberculosis (n = 16) and nonspecific infections (n = 24) were the two most common benign pathologies. There was a significant overlap in the metabolic uptake of malignant (median SUVmax-11.2, range: 3.3-34.6) and tuberculous nodules (median SUVmax-10.3, range: 2.7-22.5) with no statistically difference between their SUVmaxvalues (P = 0.43). The false-positive rate was 65.2% and the false-negative rate was 5.5%. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FDG-PET/CT for detecting malignancy were 94.4%, 34.7%, 81.9%, 66.6%, and 79.5%, respectively. CONCLUSIONS Though FDG-PET scans show a very high sensitivity for malignant nodules, it has a high false-positive rate and reduced specificity when characterizing SPNs in an infectious endemic region. Physicians must be aware of this limitation in the workup of lung nodules, and regional variations must be considered before further management decisions are taken.

Abstract
AIMS The role of whole brain radiotherapy (WBRT) in patients with brain metastases from non-small cell lung cancers (NSCLC) has been questioned. However, no reliable criteria exist to identify patients who do not benefit from WBRT. The objective of the current study was to develop a prognostic model to identify such patients whose survival matches that of the Quality of Life after Treatment for Brain Metastases (QUARTZ) study. MATERIALS AND METHODS Outcome data of patients with NSCLC with brain metastases undergoing WBRT enrolled in a prospective observational study in a tertiary cancer centre were used to develop a prognostic model. Baseline clinico-radiological factors were used for development of the model. The model was internally validated and calibration accuracy was checked for prediction of 70 day mortality. The generated prognostic model was presented as a nomogram. RESULTS The median overall survival of 140 patients enrolled in the study was 166 days (95% confidence interval 108-242 days). The prognostic model identified gender, Karnofsky performance status and epidermal growth factor receptor activating mutation status as significant factors influencing overall survival. The model showed a modest discriminative ability with an optimism-corrected C-index of 0.64. However, model calibration error did reveal a moderate degree of calibration error. The high-risk subgroup identified by the model had a median overall survival of 67 days (95% confidence interval 56-101 days), which was similar to that observed in the QUARTZ trial. CONCLUSION This prognostic model derived from traditional clinico-radiological features had a modest ability to identify patients with poor prognosis who may not benefit from WBRT. However, the high-risk subgroup identified using this prognostic model had a survival similar to that observed for patients in the QUARTZ trial.

Abstract
INTRODUCTION Testing for echinoderm microtubule-associated protein-like 4 (EML4) anaplastic lymphoma kinase (ALK) translocation by fluorescence in situ hybridization (FISH) is well established whereas the Food and Drug Administration (FDA) ALK immunohistochemical (IHC) test is relatively new. AIMS AND OBJECTIVE The aim of this study is to compare FDA-approved ALK IHC test (D5F3 clone) with the standard ALK FISH test. MATERIALS AND METHODS A validation and a test arm with 100 and 200 cases of Formalin-Fixed, Paraffin-embedded blocks of lung adenocarcinoma, respectively, comprised the material. All cases had ALK IHC test on automated Ventana Benchmark XT IHC slide stainer using anti-ALK D5F3 rabbit monoclonal primary antibody; when positive tumor cells (any percentage) showed strong granular cytoplasmic staining. For the FISH test, Vysis ALK Dual Color Break Apart Rearrangement Probe (Abbott Molecular Inc.,) was used to detect ALK gene 2p23 rearrangements; when positive the red and green signals were split two signal diameter apart and/or isolated 3'red signal were detected in more than 15% tumor cells. The ALK FISH results were available in all 100 validation cases and 64-test arm cases which formed the basis of this analysis. RESULTS The ALK IHC test was positive in 16% cases; four discordant cases were ALK IHC positive but ALK FISH negative, but no case was ALK IHC negative and ALK FISH positive. There was 100% sensitivity, 90.5% specificity, and 93.75% accuracy. CONCLUSION A negative ALK IHC result obviates the need for a FISH test barring those with a strong clinical profile, and a positive ALK IHC result is sufficient basis for the initiation of treatment.

Abstract
BACKGROUND We tested the hypothesis that telephonic follow-up (FU) may offer a convenient and equivalent alternative to physical FU of radically treated lung cancer patients. DESIGN Prospective study carried out at a tertiary referral cancer care institute, Mumbai. MATERIALS AND METHODS Two hundred consecutive lung cancer patients treated with curative intent were followed up regularly with telephonic interviews paired with their routine physical FU visits. Patient satisfaction with the telephonic call and the physical visit, the anxiety level of the patient after meeting the physician and the economic burden of the visit to the patient were noted in a descriptive manner. Kappa statistics was used to assess concurrence between the telephonic and physical impression of disease status. RESULTS With a median FU duration of 21.5 months, the median satisfaction scores for telephonic and physical FU were 8 and 9, respectively. The prevalence and bias adjusted kappa (PABAK) score of the entire cohort of patients was 0.64 (95% confidence interval [CI] =0.58-0.70). Data analyzed up to first disease progression/relapse on FU had a PABAK score of 0.71 (95% CI = 0.64-0.77) indicating substantial agreement. Patients with disease controlled at the FU had a significant PABAK score of 0.88 (95% CI = 0.80-0.94) indicating excellent concurrence. On average, each patient spent Rs. 5117.10 on travel and Rs. 3079.06 on lodging per FU visit. CONCLUSION Telephonic FU is substantially accurate in assessing disease status until the first relapse. In a resource-constrained country like India, it is worthwhile to further explore the benefits of such an alternative strategy.

Abstract
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 45-year-old premenopausal woman presented with multifocal cancer in the right breast, with lesions at 1:00 and 4:00, the largest measuring approximately 3 cm on exam, and multiple palpable right axillary lymph nodes. A core biopsy confirmed invasive ductal carcinoma, grade 2 of 3, that was estrogen receptor positive, progesterone receptor positive, and HER2 negative. Fine needle aspiration of a right axillary node confirmed metastatic carcinoma. A positron emission tomography (PET)/ computed tomography done before starting chemotherapy demonstrated an absence of metastatic disease with expected avidity in two separate breast masses and multiple conglomerated 1-2 cm level I and II axillary lymph nodes. She received neoadjuvant chemotherapy with doxorubicin plus cyclophosphamide, followed by paclitaxel, and had a complete clinical response with resolution of the breast and axillary masses on exam. A repeat PET/computed tomography demonstrated reduced size of the breast and axillary disease, and no significant residual PET avidity. Her breast surgeon recommended a right mastectomy with axillary node dissection. As part of her multidisciplinary treatment plan, she consulted with two plastic surgeons to discuss reconstruction options. Plastic Surgeon A advised placement of an implant at the time of mastectomy while Surgeon B contrasted the pros and cons of an autologous transverse rectus abdominis muscle flap reconstruction with an implant based reconstruction. Surgeon B believed that autologous reconstruction would yield the best long-term cosmetic outcome. Before making her surgery decision, the patient consulted with a radiation oncologist to discuss the effect radiation may have on her reconstruction outcome.
