RESUMO
Purpose: Multimodality imaging can enhance the precision of tumor delineation for intensity modulated radiation therapy planning. This study aimed to analyze intermodality variation for gross tumor volume (GTV) delineation in locally advanced oropharyngeal carcinomas (LAOCs). Methods and Materials: We examined the pretreatment contrast-enhanced computed tomography (CECT), magnetic resonance imaging (MRI), and fluoro-deoxy-glucose-based positron emission tomography (FDG-PET) image data sets of 33 adult patients with primary LAOC. Automatic segmentation method was used to derive PET-based metabolic tumor volumes (MTVs) at 30%, 40%, 50%, 60%, and 70% of the primary tumor's maximum standardized uptake value (SUVmax). The geometric conformality or spatial overlap was assessed using the Dice similarity coefficient (DSC), which ranges from 0 to 1, indicating no overlap to complete overlap. Results: The size of the tumor in the anteroposterior dimension of the GTV was found to be more on CT than MRI, with a mean difference of 0.29 cm (P value .015). Overall, PET-based MTV volumes were smaller than GTVs on CT and MR. Among various intensities on PET, MTV30 was the closest match with GTV-CT/MR. The mean difference for absolute tumor volumes (GTV-CT, GTV-MR, and MTV30) was not statistically significant; however, spatial overlap by DSC score was average, that is, <0.7. DSC was 0.65 ± 0.15 between GTV-CT and GTV-MR, 0.62 ± 0.15 between GTV-CT and MTV30, and 0.576 ± 0.16 between GTV-MR and MTV30 pairs, respectively. On qualitative analysis, overall tumor extension into adjacent muscles, parotid gland, retromolar trigone, and marrow infiltration of mandible was better appreciated on MRI. Conclusions: Given the significant spatial variation, multimodality imaging can serve as an excellent complement for target volume delineation on CT scans during intensity modulated radiation therapy planning for LAOC by harnessing the improved soft tissue definition of MRI and the ability of PET to provide metabolic activity information.
RESUMO
PURPOSE: There is currently no gold standard for the management of acute radiation enteritis. We compared the efficacy and safety of Racecadotril, an anti-hypersecretory drug, versus Loperamide, an anti-motility agent, in acute radiation enteritis. METHODS AND MATERIALS: We conducted a randomized, double-masked, non-inferiority trial at a single research institute. Patients receiving curative radiation for pelvic malignancies, who developed grade 2 or 3 diarrhea (as per Common Terminology Criteria for Adverse Events, v 4.0) were included in the study. Patients in the intervention arm received Racecadotril and placebo. Patients in the control arm received Loperamide and placebo. The primary outcome was the resolution of diarrhea, 48 hours after the start of treatment. RESULTS: 162 patients were randomized between 2019 and 2022. On intention-to-treat analysis, 68/81 patients, 84%, (95% CI, 74.1%-91.2%) in the Racecadotril arm and 70/81, 86.4%, (95% CI, 77.0%-93.0%) in the Loperamide arm improved from grade 2 or 3 diarrhea to grade 1 or 0, (P= .66, χ2 test). The difference in proportion was 2.4% (95% CI: -8.5% to 13.4%). Since the upper boundary of the 95% CI crossed our non-inferiority margin of 10% (13.4%) we could not prove the non-inferiority of Racecadotril over Loperamide. Rebound constipation was more in the Loperamide arm compared to Racecadotril (17.3% vs 6.2%; P = .028) CONCLUSIONS: The non-inferiority of Racecadotril to Loperamide in acute radiation enteritis could not be demonstrated. However, Racecadotril can be the preferred drug of choice in acute radiation enteritis because Racecadotril does not affect bowel motility, achieved a high clinical success rate similar to that of Loperamide, and was associated with lesser side effects.

Sebaceous carcinoma (SC) is a malignant neoplasm demonstrating sebocytic differentiation, commonly in the periocular area. Sebocytic differentiation is recognized by multivesicular cytoplasmic clearing with frequent nuclear scalloping. The vesicles can be highlighted by immunohistochemical stains against the perilipin family proteins including adipophilin. Extraocular SC is uncommon but well reported, often in the setting of Muir-Torre syndrome; however, vulvar SC is exceptionally rare. The literature review yielded only 12 prior cases of vulvar SC, all of which showed invasion. Here we report 2 additional similar cases from 2 different institutions of an intraepithelial carcinoma with sebaceous differentiation. Histologic examination of multiple specimens from both patients showed similar features: a multifocal intraepithelial basaloid nodular neoplasm sparing the basal layer with occasional pagetoid spread. The tumor cells demonstrated a high nuclear to cytoplasmic ratio, mitoses, variably foamy vacuolated cytoplasm, and nuclear indentation. Multiple specimens from both patients showed evidence of sebaceous differentiation (substantiated by adipophilin positivity in a membranous vesicular pattern in case 1 and by androgen receptor and epithelial membrane antigen positivity in case 2), and squamous differentiation (substantiated by p63/p40 and weak CK 5/6 expression), as well as human papillomavirus (HPV) association (substantiated by p16 block positivity and detection of high-risk HPV by in situ hybridization). One case was a true in situ lesion without evidence of invasion, and the other case was predominantly an in situ carcinoma with prominent adnexal extension and focal superficial invasion of <1 mm seen in one of multiple specimens. To our knowledge, these 2 cases are the first to show a vulvar SC/carcinoma with sebaceous differentiation that is predominantly limited to the epidermis, and the first documentation of HPV infection in vulvar sebaceous neoplasms. Vulvar intraepithelial carcinoma with sebaceous differentiation is the umbrella term we chose for this entity. Whether this is a true SC in situ that is HPV positive/driven, or a vulvar intraepithelial neoplasia with sebaceous differentiation, is not entirely clear. We emphasize the importance of looking for this morphology to avoid misclassification. Due to the rarity of cases, optimal treatment at this site has not been established.

Background Calvarial Ewing tumor is a relatively rare differential among bony neoplasms. We present our experience of managing primary calvarial Ewing sarcoma (EWS), highlighting their clinical and radiological findings. Method In a retrospective analysis, we evaluated our 12-year database for pathologically proven EWS. A literature search was conducted for the comparative presentation and update on the management and outcome. Result From January 2008 to December 2020, we managed eight patients (male:female = 5:3; age range 6 months to 19 years, mean 11.5 years) harboring primary calvarial EWS. All cases underwent wide local excision; two patients required intradural tumor resection, while one required rotation flap for scalp reconstruction. Mean hospital stay was 8 days. All patients received adjuvant chemo- and radiotherapy. Three patients remained asymptomatic at 5 years of follow-up, while two patients died. Conclusion Primary calvarial EWS is a rare entity. It usually affects patients in the first two decades of life. These tumors can be purely intracranial, causing raised intracranial pressure symptoms, which may exhibit rapidly enlarging subgaleal tumors with only cosmetic deformities or symptoms of both. Radical excision followed by adjuvant therapy may offer a favorable long-term outcome.

Purpose: To compare the rectal and bladder doses using two different vaginal packing techniques among uterine cervical cancer patients receiving high-dose-rate (HDR) intracavitary brachytherapy (ICBT). Material and methods: Forty-five patients with cervical cancer were randomized to receive two sessions of ICBT using tandem and ring applicator (Varian©), following completion of pelvic external beam radiotherapy treatment. The procedure was performed with vaginal balloon plus gauze packing or vaginal gauze packing alone, each of which was used in one of two sessions. Sequence of the type of vaginal packing was chosen with computer-generated block randomization. A HDR dose of 8.5 Gy was prescribed to point A in all patients. Volumetric dose parameters, such as D0.1cc, D0.5cc, D1cc, and D2cc of the rectum and bladder were compared between the two techniques of vaginal packing. Results: The mean age of patients was 51 years. Majority (88%) of patients had locally advanced stages of cancer at baseline (stage IIB or more). Rectal doses were significantly less in combined packing technique (D0.1cc: 7.52 Gy vs. 9.02 Gy, p = 0.01; D0.5cc: 6.46 Gy vs. 7.42 Gy, p < 0.01; D1cc: 5.91 Gy vs. 6.7 Gy, p < 0.01; D2cc: 5.29 Gy vs. 5.97 Gy, p < 0.01). Bladder doses were higher in the combined packing technique (D0.1cc: 11.20 Gy vs. 10.76 Gy, p = 0.18; D0.5cc: 9.64 Gy vs. 9.32 Gy, p = 0.56; D1cc: 8.64 Gy vs. 8.36 Gy, p = 0.55; D2cc: 7.56 vs. 7.33 Gy, p = 0.55). Conclusions: Combined vaginal packing resulted in statistically significant reduction in rectal radiation dose compared with standard vaginal gauze packing in high-dose-rate brachytherapy of cervix cancer using tandem and ring applicators.
RESUMO
To evaluate the safety and feasibility of treating stage I-IV endometriosis patients with robotic single-site surgery (RSSS). A retrospective chart review was conducted on 334 patients with endometriosis treated by a single surgeon at a university hospital from January 2015 to November 2019. Surgeries were performed in a single institution between 2015 and 2019. All patients presented with pelvic pain and underwent surgical resection of the lesion. American Society of Reproductive Medicine (ASRM) standards were used to classify endometriosis. The primary goal of this study is to investigate the feasibility and safety of RSSS for surgical resection of stage I-IV endometriosis patients. We will compare patient characteristics and surgical parameters, such as blood loss, operating time, and postoperative complications, across different endometriosis stages to evaluate the effectiveness of this novel technique. RSSS was used for all cases, with no conversions to laparotomy or traditional laparoscopy. One to two additional ports were placed in 41 patients with deeply infiltrating endometriosis (DIE) involving the colorectal and urinary tract and/or extensive pelvic adhesions. Across patient groups, there were no significant differences in age, BMI, fertility history, abdominal surgery history, and hysterectomy ratio (P > 0.05). The median operation time was 140.25 min (range: 85.50-260.00 min, P < 0.05) and median blood loss was 31.25 mL (range: 15-100 mL, P < 0.05). Histopathology supported the diagnosis in 259/334 patients. The undiagnosed patients were associated with lower ASRM scores. For 83.3% of patients (295/334), the length of hospital stay was < 24 h. The postoperative complication rate was 6.0% (20/334), although only two cases were severe. Our results indicate that RSSS is an alternative, safe, and acceptable platform for the surgical treatment of all stages of endometriosis.

CONTEXT.: Program requirements for Selective Pathology fellowships in the United States were established by the Accreditation Council for Graduate Medical Education (ACGME) in 2011 to govern fellowships providing advanced training in surgical pathology, focused anatomic pathology, or focused clinical pathology. Selective Pathology entered the ACGME's Next Accreditation System in 2015 with the introduction of the Selective Pathology Milestones 1.0, a set of benchmarks for evaluating fellow progress in each of the 6 ACGME core competencies. In 2019, the ACGME convened a work group for a planned periodic update to these milestones. OBJECTIVE.: To summarize changes to the Selective Pathology milestones. DESIGN.: The study design featured expert opinion and survey. RESULTS.: The Patient Care milestones for anatomic pathology-focused fellowships contain a renewed emphasis on both gross and microscopic examination, whereas for clinical pathology-focused fellowships, the emphasis is on interpretation of laboratory assays. The milestones for the non-Patient Care, non-Medical Knowledge competencies have been updated to a harmonized set of milestones designed to extend across all specialties and subspecialties. New to the milestones program is a supplemental guide that provides examples, suggested assessment tools, and references to aid in implementation. Public comments were supportive of the changes. CONCLUSIONS.: The Milestones 2.0 are set for implementation in July 2021. Updates in the new milestones are aimed at facilitating training and harmonizing evaluation across subspecialties.

INTRODUCTION: The complexity of modern-day radiotherapy techniques calls for greater accuracy in target volume delineation which requires intensive training and expert guidance. In this study, we intend to evaluate the status of training in target delineation across radiation oncology curriculums in India and utility of webinars in teaching it. METHODOLOGY: We organized daily webinars on the topics of radiological anatomy and target volume delineation in common sites of cancer over a period of 2 weeks. At the end of the program, a 35 item survey questionnaire was shared with the participants. The responses were analysed and are reported here. RESULTS: Out of the 797 participants that registered for the course, 356 radiation oncologists responded to the survey questionnaire. Majority (96%) of our respondents believe that there is a need for additional training in target volume delineation. Ninety percent of the participants felt that radiation oncology curriculum requires a formal radiology training but only 6.7% reported that their training consisted of a dedicated rotation and regular lectures in radiological anatomy. Majority (97%) responded that they were likely to incorporate the points learnt from the webinar sessions in their daily practice. Forty eight percent of respondents opted for attending a webinar to an in-person event in the future while 34% would like to have the option to choose between the two. Ninety four percent agreed that online webinars should be conducted routinely even after the pandemic ends. CONCLUSION: Our survey results suggest that target volume delineation training in India is deficient and virtual teaching programs can be a practical and effective way to improve it.

BACKGROUND: Pandoraea apista is predominantly recovered from the respiratory tract of patients with cystic fibrosis (CF). Authors report first case of central nervous system infection by P. apista in the form of skull base osteomyelitis. CASE DESCRIPTION: A 67-year-old male presented with complaints of earache and hearing deficit for few months. The radiology was suggestive of skull base osteomyelitis and polypoidal soft tissue extending from the middle cranial fossa to the infratemporal fossa. The sample from the targeted area revealed P. apista on matrix-assisted laser desorption ionization-time-of-flight mass spectrometry. With adequate antibiotic therapy, there was clinicoradiologic improvement. P. apista is an infection exclusively seen in pulmonary infection in patients with CF. We identified its intracranial involvement in a patient for the 1st time in the literature. The serendipitous diagnosis needs evaluation on specific PCR and matrix-assisted laser desorption spectrometry. The treatment with antibiotics provides a definite cure. CONCLUSION: We report a rare opportunistic infection with central nervous system involvement which can be cured by accurate diagnosis and appropriate antibiotic treatment.
RESUMO
Even for seasoned neurosurgeons who have mastered the microvascular decompression (MVD) techniques, trigeminal neuralgia (TGN) secondary to vertebrobasilar dolichoectatic vessels remains a challenge. Often, patient is either medically infirm or unwilling for invasive surgical interventions. Alternative treatment options including Gamma Knife radiosurgery (GKRS) are considered in such a situation with variable success. This study aimed to evaluate the role of GKRS in patients with trigeminal neuralgia with dolichoectatic vessels and severe cross compression. We prospectively managed three male patients of intractable TGN secondary to dolichoectatic vascular compression with single-session GKRS. The cisternal component of the trigeminal nerve was targeted with 90 Gy radiation at 100% isodose with a single 4-mm collimator. The patients were regularly evaluated on clinical parameters for pain relief (Barrow Neurological Institute (BNI) score), sensory complaints, and outcome. All patients had satisfactory pain control (BNI I-IIIa) at 3 months of interval only to get recurrent pain (BNI IV-V) after 6 months. The treatment was eventually considered a failure after 6-month duration and one patient needed MVD for pain control. Post-GKRS pain control remains inferior in patients with dolichoectasia compared with typical TGN. GKRS should be offered only as a salvage or rescue procedure and should not be used as an alternative treatment of MVD in patient population with dolichoectatic vessels.
RESUMO
Cavernous sinus hemangioma (CSH) are notoriously difficult to excise because of their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures. Radiosurgery offers an alternative treatment modality in cases of small and medium-sized CSH. However, no reports are available in the world literature detailing gamma knife radiosurgery (GKRS) in large (3-4 cm) and giant (>4 cm) CSH. Two patients with giant CSH (Tumor volume was 72.2 and 99.8 cm3, respectively) were treated with frame-based fractionated GKRS (5 Gy × 5 #). The treatment was done with Leksell Perfexion with frame in situ and interfraction interval of 24 h. The tumor was engulfing the optic apparatus, and chiasma could not be separated delineated. The patients were followed at 3 months interval with clinic-radiologic evaluation. Following GKRS, both patients showed remarkable clinical improvement in presenting complaints of headache and visual deterioration. Sixth nerve paresis recovered completely in case no. 1. Significant reduction in tumor volumes (85.1 and 75.6% respectively) was noticed in both the patients at 6 months follow-up radiology. Transient alopecia was noted in case 1 at 3 months follow-up that completely resolved by the 6 months. There was no complication till the last follow-up of 9 months. We report the first account of five fraction frame-based hypo fractionated GKRS for giant CSH. At an interval as short as 3 months, giant CSH shows remarkable clinical improvement. Primary hypofractionated GKRS may be considered an alternative effective modality in these difficult lesions with a favorable safety profile.

OBJECTIVE: To evaluate the inter- and intra-rater variability of lymphovascular space invasion (LVSI) in early stage cervical cancer. METHODS: We identified invasive cervical cancer tissue samples from radical hysterectomies in our institutional pathology database. The cases were stained with Hematoxylin & Eosin (H&E) and immunostains (CD-31 and D2-40). They were evaluated for the presence of LVSI by 6 pathologists on 3 separate occasions: with H&E staining only, then with H&E and immunostained specimens, and finally using a shared written criterion for diagnosis of LVSI. With 80 cases, a two-sided 95% confidence interval for the Kappa of 0.7 with a precision of 0.1 on each side was estimated. RESULTS: Stage distribution was: IA 10%, IB 85%, and IIA 5%. The majority of cases were squamous cell carcinoma (55%), followed by adenocarcinoma (39%) and adenosquamous or other histology (6%). The mean inter-rater Kappa was 0.41 (95% CI: 0.37-0.45) for H&E. Usage of immunohistochemistry made a statistically significant improvement in the mean Kappa, but it still remained low: 0.52 (p = 0.02). Adding evaluation criteria for LVSI did not significantly increase the mean Kappa: 0.49 (p = 0.16). The mean intra-rater variability of H&E staining alone compared with H&E staining plus immunostaining was 0.53 (range: 0.43-0.64). The mean Kappa comparing H&E staining and H&E staining with criteria was 0.50 (range: 0.40-0.59). CONCLUSIONS: We noted high inter- and intra-rater variability in the diagnosis of LVSI underscoring the challenges of LVSI diagnosis. Considering the significance assigned to LVSI and its implication for treatment, comprehensive guidelines with regards to determination of LVSI status are of paramount importance.

We describe 22 examples of a novel, usually paratubal, adnexal tumor associated with Peutz-Jeghers syndrome in nearly 50% of cases that harbored STK11 alterations in all tested (n=21). The patients ranged from 17 to 66 years (median=39 y) and the tumors from 4.5 to 25.5 cm (median=11 cm). Most (n=18) were paratubal, with metastases noted in 11/22 (50%) and recurrences in 12/15 (80%). Morphologically, they were characterized by interanastomosing cords and trabeculae of predominantly epithelioid cells, set in a variably prominent myxoid to focally edematous stroma, that often merged to form tubular, cystic, cribriform, and microacinar formations, reminiscent of salivary gland-type tumors. The tumor cells were uniformly atypical, often with prominent nucleoli and a variable mitotic index (median=9/10 HPFs). The tumors were usually positive to a variable extent for epithelial (CAM5.2, AE1/AE3, cytokeratin 7), sex cord (calretinin, inhibin, WT1), and mesothelial (calretinin, D2-40) markers, as well as hormone receptors. PAX8, SF1, and GATA-3 were rarely positive, while claudin-4, FOXL2, and TTF-1 were consistently negative. All sequenced tumors (n=21) harbored alterations in STK11, often with a loss of heterozygosity event. There were no other recurrently mutated genes. Recurrent copy number alterations included loss of 1p and 11q, and gain of 1q, 15q, and 15p. Despite an extensive morphologic, immunohistochemical, and molecular evaluation, we are unable to determine with certainty the histogenesis of this unique tumor. Wolffian, sex cord stromal, epithelial, and mesothelial origins were considered. We propose the term STK11 adnexal tumor to describe this novel entity and emphasize the importance of genetic counseling in these patients as a significant number of neoplasms occur in association with Peutz-Jeghers syndrome.

Despite widespread popularity of navigation and angled endoscopes in endonasal endoscopy, there are hardly few studies on their efficacy with the extent of resection or retreatment. This is probably the first study to assess the independent impact of these adjuncts among pituitary tumors. Patients with pituitary tumors undergoing endonasal endoscopy were prospectively studied for their demographics, clinico-radiological features, intraoperative use of navigation, and angled endoscopes, in relation to gross total resection (GTR), near total resection (NTR), endocrine remission, and retreatment. Pertinent statistical analyses were performed. Among a total of 139 patients, navigation and angled endoscopes could be used in 54 and 48 patients, respectively, depending upon their availability rather than chosen as per the case. There was no significant difference in baseline characteristics in relation to their use. The surgeon's perception of immediate benefit was noted among 51.9% while using navigation. The use of angled endoscopes towards the end of resection could help with additional tumor removal in 62.5% of patients. Overall, the use of navigation resulted in a significantly higher GTR (80.8% vs. 59.7%, OR 2.83, p = 0.01), a higher GTR/NTR (86.5% vs. 70.8%, OR 2.65, p = 0.04), and a lower retreatment rate (7.7% vs. 20.8%, OR 3.15, p = 0.05) than the others. In functioning tumors with cavernous sinus invasion, navigation had significantly increased remission rates (69.2% vs. 0%, p = 0.03). The use of angled endoscopes yielded a significantly higher GTR/NTR (91.7% vs. 70.6%, p = 0.04) and a lower retreatment rate (0% vs. 15.7%, p = 0.05) among only non-functioning adenomas. In multivariate analyses, the use of neuronavigation had a significant association with both GTR and retreatment rates (p values 0.005 and 0.02 respectively), independent of other confounding factors. The elective intraoperative use of navigation has a significant independent impact on the extent of resection and retreatment overall. While navigation results in better remission rates among functioning tumors with cavernous sinus invasion, angled endoscopy has a significant association with surgical outcomes in non-functioning tumors.

BACKGROUND: Spinal dysraphic anomalies may be hidden beneath grotesque cutaneous stigmata, like a fully developed accessory lower limb. CASE DESCRIPTION: Authors describe a 4-year-old boy who had socially unacceptable malformation in form of an accessory lower limb, in addition to perfectly normal both lower limbs with underlying low-lying tethered cord. Radiological studies showed underlying tethered cord and dysraphic spinal column. CONCLUSION: Successful surgical correction was undertaken along with detethering of cord. The present case asks for evaluation of all cutaneous stigmata over spinal regions in newborns for spinal dysraphic states.

INTRODUCTION: Severe acute respiratory syndrome, coronavirus 2 (SARS-COV 2) has inexplicably and irreversibly changed the way of neurosurgery practice. There has been a substantial reduction in neurosurgical operations during the period of lockdown. The lockdown might be the most effective measure to curtail viral transmission. Once we return to the normalization of the lifestyle, there will be a backlog of unoperated pending cases along with the possibility of further spread of the coronavirus. METHODS: We reviewed the available literature and protocols for neurosurgical practice in different geographic locations. We drafted a consensus statement based on the literature and protocols suggested by the World Health Organization (WHO) and various professional societies to prevent the spread of SARS-COV2 while streamlining the neurosurgical practice. RESULTS: The consensus statement suggests the patient triage, workflow, resource distribution, and operational efficacy for care providers at different stages of management. The priority is set at personal protection while ensuring patients' safety, timely management, and capacity building. We performed a detailed subsection analysis for the management of trauma and set up for COVID-free hospitals for simultaneous management of routine neurosurgical indications. In this time of medicolegal upheaval, special consent from the patients should be taken in view of the chances of delay in management and the added risk of corona infection. The consensus statements are applicable to neurosurgical setups of all capacities. CONCLUSION: Along with the glaring problem of infection, there is another threat of neurosurgery emergency building up. This wave may overwhelm the already stretched systems to the hilt. We need to flatten this curve while avoiding contagion. These measures may guide neurosurgery practitioners to effectively manage patients ensuring the safety of caregivers and care seekers both.

BACKGROUND: Superficial angiomyxoma (SAM) is a rare, benign cutaneous tumor. Originally described as a component of Carney complex, it is now recognized as a sporadic condition. CASE: A 7-year-old girl was referred for management of a 2.5-cm mass arising from the right labia majora. Key pathologic features included lobules of spindle-shaped cells in a myxoid matrix and prominent neutrophilic infiltrate. The cells were positive for CD34 and negative for desmin, progesterone receptor, and estrogen receptor staining. SUMMARY AND CONCLUSION: This case is that of the youngest described patient with vulvar SAM. Patients should be carefully examined for manifestations of Carney complex to avoid potentially life-threatening complications. It is critical to distinguish SAM from aggressive angiomyxoma. The patient was referred to genetics and will be followed for local recurrence.
