BACKGROUND
Pancoast tumors represent 5% of non-small cell lung cancers. Complete surgical resection and no lymph node involvement are important positive prognostic factors. Previous literature has identified neoadjuvant chemoradiation treatment, followed by surgical resection, as the standard of care. But many institutions choose upfront surgery. Our goal was to identify the treatment patterns and outcomes in patients with node-negative Pancoast tumors using the National Cancer Database (NCDB).
METHODS
The NCDB was queried from 2004 through 2017 to identify all patients who had undergone surgery for a Pancoast tumor. Treatment patterns, including the percentage of patients who received neoadjuvant treatment, were recorded. Logistic regression and survival analyses were used to determine outcomes based on different treatment patterns. Secondary analyses were performed on the cohort who received upfront surgery.
RESULTS
A total of 2,910 patients were included in the study. Overall 30- and 90-day mortality were 3% and 7% respectively. Only 25% (717/2,910) of the group received neoadjuvant chemoradiation treatment prior to surgery. Patients who received neoadjuvant chemoradiation treatment experienced significantly improved 90-day survival (P<0.01) and overall survival (P<0.01). When analyzing the cohort who received upfront surgery, there was a statistically significant difference in survival based on adjuvant treatment pattern (P<0.01). Patients in this group who received adjuvant chemoradiation had the best survival, whereas patients who received adjuvant radiation only or no treatment had the worst outcomes.
CONCLUSIONS
Patients with Pancoast tumors receive neoadjuvant chemoradiation treatment in only a quarter of cases nationally. Patients who received neoadjuvant chemoradiation treatment had improved survival compared to patients who had upfront surgery. Similarly, when surgery is performed first, adjuvant chemoradiation treatment improved survival compared to other adjuvant strategies. These results suggest underutilization of neoadjuvant treatment for patients with node-negative Pancoast tumors. Future studies with a more clearly defined cohort are needed to assess the treatment patterns being utilized on patients with node-negative Pancoast tumors. It will be beneficial to see whether neoadjuvant treatment for Pancoast tumors has increased in recent years.

Pancoast tumor is a rare and aggressive form of lung cancer; cardiac metastasis is very uncommon. We present a case of advanced Pancoast tumor, with extensive cardiac metastases and intracardiac thrombosis in a woman presenting with dyspnea, shoulder pain, and weight loss. A contrast-enhanced chest computed tomographic scan revealed an apical mass, metastatic thoracic nodes, and filling defects within both ventricles. Further imaging with cardiac magnetic resonance imaging revealed 2 left ventricular masses infiltrating into the myocardium suggestive of metastatic disease, and a multilobulated mass within the right ventricle suggestive of intracardiac thrombus. She was initiated on anticoagulation for intracardiac thrombosis. Surgical pathology of biopsied tissue samples was consistent with advanced metastatic lung adenocarcinoma. She was a poor candidate for surgical intervention. Given the patient's goals of care, she was ultimately transitioned to comfort care.

BACKGROUND
Horner's syndrome (HS) classically consists of the symptom triad of miosis, ptosis, and anhidrosis. It is caused by impairment of a certain pathway in the sympathetic nervous system. It may also appear as part of the clinical signs of other diseases and syndromes, including Pancoast tumors, intradural and/or epidural tumors, thoracic outlet syndrome, syringomyelia, brachial plexus injury, and aortic dissection. Here, we report a very rare complication of vertebral column resection in children, and we present the clinical findings of a case of Horner's syndrome with a current literature review.
CASE PRESENTATION
A five-year-old child with severe congenital kyphoscoliosis qualified for surgical treatment of the spinal deformity via a posterior approach, with three-column osteotomy and fusion.
RESULTS
After successful surgery, the patient presented with HS due to distraction of the sympathetic nerve trunk and, thus, innervation to the left eye. At the 4-year follow-up, the child had fully recovered.
CONCLUSIONS
Pediatric HS after posterior instrumented scoliosis correction surgery with posterior vertebral column resection of the thoracic spine is very rare. This is the first reported case of HS after posterior vertebral column resection and spinal fusion for congenital kyphoscoliosis without the use of epidural analgesia. Symptom resolution may be variable and, in some cases, delayed.

Surgical treatment of superior sulcus tumors (SSTs) is clinically challenging. Definitive chemoradiotherapy (CRT) is a standard treatment for SST. In operable cases, multimodal therapy (CRT followed by surgery) is another option, at least for experienced institutions. Immune checkpoint inhibitors (ICIs) have recently been developed, and several clinical trials have investigated definitive CRT followed by ICIs for consolidation or maintenance therapy of unresectable local advanced non-small cell lung cancer (NSCLC), including SSTs. Clinical studies of salvage surgery after CRT followed by ICIs are also ongoing. However, the clinical outcomes of salvage surgery after multimodal therapies and histopathological analyses of surgical specimens after such treatments remain unclear. Here, we report the case of a patient with SST comprising squamous cell carcinoma with invasion of the second to third rib and vertebrae who underwent salvage surgery after concurrent definitive CRT followed by the ICI durvalumab, and show the results of clinicopathological analyses of the resected specimen.

OBJECTIVES
En-bloc complete resection remains the treatment of choice for localized chest wall (CW) tumors. Titanium bars reconstruction demonstrated encouraging results with satisfactory early outcomes. However, long-term outcomes remain under-reported. The purpose of this study is to evaluate long-term outcomes after CW resection and repair with titanium devices.
METHODS
From June 2012 to December 2018, we retrospectively reviewed all patients with CW tumors who underwent surgical resection and repair using titanium. Long-term outcomes were assessed.
RESULTS
We identified 87 patients who underwent CW tumor resections and titanium reconstruction. Sixty-eight patients were included in the study (excluding benign tumors, Pancoast tumors, palliative surgeries, or clavicle reconstruction). There were 29 sarcomas, 20 isolated CW metastases, eight lung cancers, four breast cancers, three thymic malignancies, two sarcomatoid mesothelioma, and one desmoid tumor. Complete resection was achieved in 64 patients (94%), while R1 resection in four patients (6%). Resection involved one rib in two patients, two ribs in thirteen, three ribs in eighteen, four ribs in nine, five ribs in two, seven ribs in one, partial sternum in fifteen, and full sternum in sixteen patients. No patient experienced flail chest. The 1-year, 3-year, and 5-year overall survival rates and disease-free survivals were 82.3%, 61.4%,57.3%, and 67.6%,57.3%,52.6%, respectively. Surgical site infection occurred in 18% ( = 12) of cases. Eleven of twelve patients had an early infection (<1 year), which required material removal in six patients. Asymptomatic connector unsealing occurred in 6% ( = 4), with only one re-intervention. Titanium allergy has never been reported. Chronic chest pain (lasting more than 3 months after surgery, with daily use of pain killer) was reported in 24% of patients.
CONCLUSION
CW resections with titanium reconstruction are associated with long-term survivors. Titanium devices were safe, reliable, and achieved satisfactory oncological results with low morbidity and implant-related complication rates.

Review
BACKGROUND Pancoast tumors, also called superior sulcus tumors, are a rare type of cancer affecting the lung apex. These tumors can spread to the brachial plexus and spine and present with symptoms that appear to be of musculoskeletal origin. CASE REPORT A 59-year-old Asian man presented to a chiropractor in Hong Kong with a 1-month history of neck and shoulder pain and numbness that had been treated unsuccessfully with exercise, medications, and acupuncture. He had an active history of tuberculosis, which was currently treated with antibiotics, and a 50-pack-year history of smoking. Cervical magnetic resonance imaging (MRI) was performed urgently, revealing a small cervical disc herniation thought to correspond with radicular symptoms. However, as the patient did not respond to a brief trial of care, a thoracic MRI was urgently ordered, revealing a large superior sulcus tumor invading the upper to mid-thoracic spine. The patient was referred for medical care and received radiotherapy and chemotherapy with a positive outcome. A literature review identified 6 previously published cases in which a patient presented to a chiropractor with an undiagnosed Pancoast tumor. All patients had shoulder, spine, and/or upper extremity pain. CONCLUSIONS Patients with a previously undiagnosed Pancoast tumor can present to chiropractors given that these tumors may invade the brachial plexus and spine, causing shoulder, spine, and/or upper extremity pain. Chiropractors should be aware of the clinical features and risk factors of Pancoast tumors to readily identify them and refer such patients for medical care.

Multiple myeloma is a neoplastic proliferation of immunoglobulin-producing plasma cells with clinical features resulting from infiltration of plasma cells into bones and other organs. Multiple myeloma manifesting as an apical lung mass is less common and very few cases have been reported. We report the case of a 50-year-old female who presented with an apical lung mass which happened to be multiple myeloma arising from the upper ribs into the lung. At the time of diagnosis, patient had axillary lymph node metastasis with extensive bony involvement. This case report and literature review provides insight to a rare but significant presentation of multiple myeloma and highlights the need to consider multiple myeloma as a possible differential for Pancoast tumor in the appropriate clinical setting as this could potentially affect management options and patient outcome.

Asian Spine Journal Oct 2022Retrospective cohort study.
STUDY DESIGN
Retrospective cohort study.
PURPOSE
This study aimed to evaluate the outcomes of patients who had T4 Pancoast tumors invading the spine and underwent en bloc resection and spinal stabilization through a single-stage posterior approach.
OVERVIEW OF LITERATURE
Surgical resection for Pancoast tumors affecting the spine has been successfully performed in two stages involving spinal reconstruction and tumor resection. However, reports have rarely presented the results of en bloc resection combined with spinal stabilization for T4 Pancoast tumors invading the spine through a single-stage posterior approach.
METHODS
Patients who had T4N0M0 Pancoast tumors invading the spine and underwent a single-stage posterior approach were retrospectively recruited. The following data were obtained and examined: demographics, tumor histology, preoperative and postoperative therapy, complications, spinal reconstruction technique, tumor resection extent, survival time, and disease recurrence.
RESULTS
Eighteen patients were included. The mean population age was 61±17 years, and the most common pathological type was adenocarcinoma (61.1%). Complete resection (R0) was obtained in 15 patients (83.3%), positive surgical margins (R1) were found in three patients (16.7%), and the 90-day mortality rate was 0%. Postoperative major complications were detected in 12 patients (66.7%), who required reoperation. The mean survival time was 67±24 months, but the median survival time was not reached. Among the patients, 10 (55.6%) are still alive at the end of the study. The 2- and 5-year actual survival rates were 59% (95% confidence interval [CI], 35.7%-82.3%) and 52.5% (95% CI, 28.4%-76.6%), respectively.
CONCLUSIONS
En bloc resection and spinal stabilization through a single-stage posterior approach might be effective for T4 Pancoast tumors invading the spine.

A 55-year-old man presented with upper backache for one month, inability to move both the lower limbs for two weeks and retention of urine for five days. Examination revealed spastic paraplegia and reduced breath sounds in the right upper zone. Initial imaging revealed a soft tissue lesion in the apex of the right lung, suggesting a Pancoast tumor. It also showed a lytic, expansile lesion of the T2 vertebra extending to the right second posterior rib on subsequent imaging. High serum calcium, M-spike in beta-gamma globulin region on serum electrophoresis, 50%-60% plasmacytoid cells on bone marrow aspiration, concertina collapse of the vertebral body, and pattern of neurological deficit pointed towards multiple myeloma. T2 corpectomy and mesh cage placement, C7-T4 posterior stabilization, and resection of the second rib were done. Histopathology confirmed multiple myeloma. Postoperatively, the patient was managed with radiotherapy and bortezomib. The patient had a good neurological recovery. Timely intervention is critical for disease control and leads to better recovery.
