Project description:ObjectivesLocally advanced non-small-cell lung cancer (NSCLC) with chest wall invasion carries a high risk of recurrence and portends poor survival (30-40% and 20-50%, respectively). No studies have identified prognostic factors in patients who underwent R0 resection for non-superior sulcus NSCLC.MethodsA retrospective review was conducted for all chest wall resections for NSCLC from 2004 to 2018. Patients with superior sulcus tumours, partial (<1 rib) or incomplete (R1/R2) resection or distant metastasis were excluded. Disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Cox proportional hazards modelling was used to determine factors associated with DFS and OS.ResultsA total of 100 patients met inclusion criteria. Seventy-three (73%) patients underwent induction therapy, and all but 12 (16%) patients experienced a partial radiological response. A median of 3 ribs was resected (range 1-7), and 67 (67%) patients underwent chest wall reconstruction. The 5-year DFS and OS were 36% and 45%, respectively. Pathological N2 status [hazard ratio (HR) 3.12, confidence interval (CI) 1.56-6.25; P = 0.001], intraoperative blood transfusion (HR 2.24, CI 1.28-3.92; P = 0.005) and preoperative forced vital capacity (per % forced vital capacity, HR 0.97, CI 0.96-0.99; P = 0.013) were associated with DFS. Increasing pathological stage, lack of radiological response to induction therapy (HR 7.35, CI 2.35-22.99; P = 0.001) and cardiovascular comorbidity (HR 2.43, CI 1.36-4.36; P = 0.003) were associated with OS.ConclusionsWe demonstrate that blood transfusion and forced vital capacity are associated with DFS after R0 resection for non-superior sulcus NSCLC, while radiological response to induction therapy greatly influences OS. We confirm that pathological nodal status and pathological stage are reproducible determinants of DFS and OS, respectively.

Project description:IntroductionCurative-intent treatment of superior sulcus tumors (SSTs) of the lung invading the spine presents considerable challenges. We retrospectively studied outcomes in a single center, uniformly staged patient cohort treated with induction concurrent chemoradiotherapy followed by surgical resection (trimodality therapy).MethodsAn institutional surgical database from the period between 2002 and 2021 was accessed to identify SSTs in which the resection included removal of at least part of the vertebral body. All patients were staged using fluorodeoxyglucose positron emission tomography (/computed tomography), computed tomography scan of the chest/upper abdomen, and brain imaging. Surgical morbidity was assessed using the Clavien-Dindo classification. Overall and disease-free survival were calculated using the Kaplan-Meier method.ResultsA total of 18 patients were included: 8 complete and 10 partial vertebrectomies were performed, with six of the eight complete vertebrectomies involving two vertebral levels, resulting in Complete surgical resection (R0) in 94%. Nine patients had a 1-day procedure, and nine were staged over 2 days. The median follow-up was 30 months (interquartile range 11-57). The 90-day postoperative morbidity was 44% (grade III/IV), with no 90-day surgery-related mortality. There were 83% who had a major pathologic response, associated with improved survival (p = 0.044). The 5-year overall and disease-free survival were 55% and 40%, respectively. Disease progression occurred in 10 patients, comprising locoregional recurrences in two and distant metastases in eight patients.ConclusionsMultimodality treatment in selected patients with a superior sulcus tumor invading the spine is safe and results in good survival. Such patients should be referred to expert centers. Future research should focus on improving distant control (e.g. [neo]adjuvant immunotherapy).

Project description:Superior pulmonary sulcus tumor is a cancer arising in the apex of the lung that with potential invasion of the brachial plexus, upper ribs, vertebrae, subclavian vessels, and stellate ganglion. Induction concurrent chemoradiotherapy followed by radical surgical resection with lobectomy combined with any structures in the thoracic inlet invaded by tumor and thorough mediastinal lymph node dissection is the preferred treatment. Both anterior and posterior approaches are applied for resection. Here, we report a 61-year-old man with an 8.6 cm × 5.1 cm mass arising from the right upper lobe invading the apex of the chest wall. Brachial plexus magnetic resonance imaging suggested tumor invasion of the inferior trunk of the brachial plexus, anterior portion of the first 2 ribs, and suspicious involvement of the subclavian artery. Biopsy of the mass showed stage cT4N2M0, IIIB, poorly differentiated adenocarcinoma. The patient was treated by induction concurrent chemoradiotherapy, which was followed by surgical resection of the right upper lobe and the affected chest wall via the transmanubrial approach. The patient suffered prolonged postoperative air leak and empyema. After continuous chest tube drainage and intrapleural fibrinolytic therapy, he recovered well and was discharged safely. Final pathology showed no viable residue tumor, pathologic complete response of the tumor to induction treatment, a tumor size of 4.1 cm, and no lymph nodes; therefore, the final stage was ypT0N0M0. The transmanubrial approach is feasible for resection of tumor invading the branches of the subclavian artery; however, postoperative empyema which might have resulted from prolonged air leak should be carefully treated by meticulous air leak management.

Project description:Humans show a remarkable ability to discriminate others' gaze direction, even though a given direction can be conveyed by many physically dissimilar configurations of different eye positions and head views. For example, eye contact can be signaled by a rightward glance in a left-turned head or by direct gaze in a front-facing head. Such acute gaze discrimination implies considerable perceptual invariance. Previous human research found that superior temporal sulcus (STS) responds preferentially to gaze shifts [1], but the underlying representation that supports such general responsiveness remains poorly understood. Using multivariate pattern analysis (MVPA) of human functional magnetic resonance imaging (fMRI) data, we tested whether STS contains a higher-order, head view-invariant code for gaze direction. The results revealed a finely graded gaze direction code in right anterior STS that was invariant to head view and physical image features. Further analyses revealed similar gaze effects in left anterior STS and precuneus. Our results suggest that anterior STS codes the direction of another's attention regardless of how this information is conveyed and demonstrate how high-level face areas carry out fine-grained, perceptually relevant discrimination through invariance to other face features.

Project description:BackgroundAlthough preoperative chemotherapy (cisplatin-etoposide) and radiotherapy, followed by surgical resection, is considered a standard of care for superior sulcus cancers, treatment is rigorous and relapse limits long-term survival. The Southwest Oncology Group-Intergroup Trial S0220 was designed to incorporate an active systemic agent, docetaxel, as consolidation therapy.MethodsPatients with histologically proven and radiologically defined T3 to 4, N0 to 1, M0 superior sulcus non-small cell lung cancer underwent induction therapy with cisplatin-etoposide, concurrently with thoracic radiotherapy at 45 Gy. Nonprogressing patients underwent surgical resection within 7 weeks. Consolidation consisted of docetaxel every 3 weeks for 3 doses. The accrual goal was 45 eligible patients. The primary objective was feasibility.ResultsOf 46 patients registered, 44 were eligible and assessable; 38 (86%) completed induction, 29 (66%) underwent surgical resection, and 20 (45% of eligible, 69% surgical, and 91% of those initiating consolidation therapy) completed consolidation docetaxel; 28 of 29 (97%) underwent a complete (R0) resection; 2 (7%) died of adult respiratory distress syndrome. In resected patients, 21 of 29 (72%) had a pathologic complete or nearly complete response. The known site of first recurrence was local in 2, local-systemic in 1, and systemic in 10, with 7 in the brain only. The 3-year progression-free survival was 56%, and 3-year overall survival was 61%.ConclusionsAlthough trimodality therapy provides excellent R0 and local control, only 66% of patients underwent surgical resection and only 45% completed the treatment regimen. Even in this subset, distant recurrence continues to be a major problem, particularly brain-only relapse. Future strategies to improve treatment outcomes in this patient population must increase the effectiveness of systemic therapy and reduce the incidence of brain-only metastases.

Project description:Facial motion plays a fundamental role in the recognition of facial expressions in primates, but the neural substrates underlying this special type of biological motion are not well understood. Here, we used fMRI to investigate the extent to which the specialization for facial motion is represented in the visual system and compared the neural mechanisms for the processing of non-rigid facial motion in macaque monkeys and humans. We defined the areas specialized for facial motion as those significantly more activated when subjects perceived the motion caused by dynamic faces (dynamic faces > static faces) than when they perceived the motion caused by dynamic non-face objects (dynamic objects > static objects). We found that, in monkeys, significant activations evoked by facial motion were in the fundus of anterior superior temporal sulcus (STS), which overlapped the anterior fundus face patch. In humans, facial motion activated three separate foci in the right STS: posterior, middle, and anterior STS, with the anterior STS location showing the most selectivity for facial motion compared with other facial motion areas. In both monkeys and humans, facial motion shows a gradient preference as one progresses anteriorly along the STS. Taken together, our results indicate that monkeys and humans share similar neural substrates within the anterior temporal lobe specialized for the processing of non-rigid facial motion.

Project description:ObjectiveDespite neoadjuvant chemoradiotherapy, Pancoast tumors still present surgical and oncologic challenges. To optimize outcomes, we used a multidisciplinary care paradigm with medical and radiation oncology, and involvement of spine neurosurgery for most T3 and all T4 tumors. Spine neurosurgery permitted resection of transverse process for T3 and vertebral body resection for T4 tumors.MethodsRetrospective analysis of single institution, prospective database of patients undergoing resection for cT3 4M0 Pancoast tumors. Patients were grouped as cT3 with combined resection with spine neurosurgery (T3 Neuro), cT3 without spine neurosurgery (T3 NoNeuro), and cT4. Overall survival, progression-free survival were analyzed by Kaplan-Meier and compared between groups using log-rank test. Cumulative incidence of local-regional and distant recurrence were compared using Gray test. P value <.05 was considered significant.ResultsFrom 2000 to 2021, 155 patients underwent surgery: median age was 58 years, and 81 were (52%) men. Most patients received neoadjuvant platinum-based neoadjuvant chemoradiotherapy (n = 127 [82%]). Operations were 48 cT3 Neuro, 41 cT3 NoNeuro, 66 cT4. R0 resection was achieved in 49 (94%) cT3 NoNeuro, 35 (85%) cT3 Neuro, and 57 (86%) cT4 patients (P = .4). Complete or major pathologic response occurred in 71 (55%) patients. Lower local-regional cumulative incidence was seen in cT3 Neuro versus cT3 NoNeuro (P = .05) and after major pathologic response. Overall survival and progression-free survival were associated with complete response, pathologic stage, and nodal status but not cT category.ConclusionsThis treatment paradigm was associated with a high frequency of R0 resection, complete response, and major pathologic response. cT3 and cT4 tumors had similar outcomes. Novel therapies are needed to improve complete response.

Project description:Chemoradiotherapy followed by surgical resection (trimodality therapy) is a guideline recommended treatment for sulcus superior tumors (SST). By definition, SSTs invade the chest wall and therefore require en-bloc chest wall resection with the upper lung lobe or segments. The addition of a chest wall resection, potentially results in higher morbidity and mortality rates when compared to standard anatomical pulmonary resection. This, together with their anatomical location in the thoracic outlet, and varying grades of fibrosis and adhesions resulting from induction chemoradiotherapy in the operation field, make surgery challenging. Depending on the exact location of the tumor and extent to which it invades the surrounding structures, the preferred surgical approach may vary, e.g., anterior, posterolateral, hemi-clamshell, or combined approach; all with their own potential advantages and morbidities. Careful patient selection, adequate staging and discussion in a multidisciplinary tumor board in a center experienced in complex thoracic oncology leads to the best long-term survival outcomes with the least morbidity and mortality. Enhanced recovery guidelines are now available for thoracic surgery, promoting faster recovery and helping to minimize complications and morbidity, including infections and thoracotomy pain. Although minimally invasive surgery can enhance recovery and reduce chest wall morbidity, and is in widespread use in thoracic oncology, its use for SST has been limited. However, this is an evolving area and hybrid surgical approaches (including use of the robot) are being reported. Chest wall reconstruction is rarely necessary, but if so, the prosthetic materials are preferably radiolucent/non-scattering, rigid enough while still being somewhat flexible, and inert, providing structural support, allowing chest wall movement, and closing defects, while inciting a limited inflammatory response. New techniques such as 3D image reconstructions/volume rendering, 3D-printing, and virtual reality modules may help pre-operative planning and informed patient consent.

Project description:BackgroundThe superior mesenteric artery (SMA)-first approach for pancreatic cancer (PC) is common surgical technique in pancreaticoduodenectomy. To date, few studies have reported SMA-first approach in robot-assisted pancreaticoduodenectomy (RPD). Herein, we present the anterior SMA-first approach for PC during RPD.Patient and methodA 75-year-old man with resectable PC underwent RPD after neoadjuvant chemotherapy. As pancreatic head tumor contacted with the superior mesenteric vein (SMV), the anterior SMA approach was applied. After the mesenteric Kocher maneuver, the jejunum was divided and the left side of the SMA was dissected. Subsequently, the anterior plane of the SMA was dissected. Following the division of branches from the mesenteric vessels, the SMA was taped, and the circumferential dissection around the SMA was performed to detach the pancreatic neck from the SMA completely. Finally, the dissection between the SMV and the tumor was performed under vascular control to remove the specimen.ConclusionsThe anterior SMA-first approach can be optional in patients with PC undergoing RPD. This unique approach allows for the circumferential dissection around the SMA during RPD.
