Review
Pancoast tumors, also defined as superior sulcus tumors, still represent a complex clinical condition requiring high technical surgical skills within more articulated multimodality treatment. The morbidity and mortality rates after Pancoast tumor treatments range from 10 to 55% and 0 to 7%, respectively, and the 5-year survival rate has significantly improved in recent years thanks to the advancement of treatments. Although a multimodality approach combining chemotherapy, radiotherapy, and surgery allows for radical resection and effective local control in the vast majority of patients, many patients cannot receive surgical resection or complete the whole programmed therapeutic regimen. Systemic relapse, particularly cerebral recurrence, still poses a significant issue in this cohort of patients. Surgical resection still plays a pivotal role within the multimodality approach. Here, we focus on surgical approaches to both anterior and posterior Pancoast tumors: the anterior transclavicular approach (Dartevelle); the anterior transmanubrial approach (Grunenwald-Spaggiari); the anterior trap-door approach (Masaoka, Nomori); the posterior approach (Shaw-Paulson); the hemiclamshell approach; and hybrid approaches. Global clinical condition, tumor histology, and long-term perspectives should always be taken into consideration when embarking on such a demanding oncologic scenario.

Review
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.

Regenerating family protein 3 A (Reg3A) is highly expressed in a variety of organs and inflammatory tissues, and is closely related to tumorigenesis and cancer progression. However, clinical statistics show that high expression of Reg3A is associated with better prognosis in colorectal cancer (CRC) patients, suggesting a tumor-suppressive effect. The precise action and underlying mechanism of Reg3A in CRC remain controversial. The present study sought to investigate the relationship among Reg3A expression, CRC development, and immune cell alteration in patients using the TCGA, GEPIA, PrognoScan, TIMER and TISIDB databases. Reg3A-overexpressing LoVo cell line (LoVo-Reg3A), a representative of colon adenocarcinoma (COAD), was constructed and the action of Reg3A was assessed in a xenograft nude mouse model. Our bioinformatical analyses revealed that Reg3A upregulation is highly associated with CRC, along with increased frequency of immune cell infiltration. In the xenograft nude mice, Reg3A overexpression offered a tumor-suppressive effect by inhibiting cell proliferation and promoting apoptosis. The result of RNA-seq suggested a positive regulation of leukocytes and an upregulation of T cells in LoVo-Reg3A tumor tissue. CD4 and CD8 T cells in tumors, splenic Reg3A-reactive IFN-γ/CD4 T cells, and serum TNF-α, IFN-γ and IL-17 were significantly increased by Reg3A overexpression. In the ex vivo co-culture experiment, elevated cytotoxic effect, increased proportion of CD3ε T cells, and upregulated expressions of TNF-α, IFN-γ and IL-17 were detected in the PBMCs isolated from LoVo-Reg3A cell-xenografted nude mice. In conclusion, high expression of Reg3A could activate and recruit T cells in COAD leading to the cytotoxic tumor-suppressive effect.

INTRODUCTION
Curative-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).
METHODS
An 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.
RESULTS
A 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 ( = 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.
CONCLUSIONS
Multimodality 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).

INTRODUCTION
Hepatocellular carcinoma is the most common primary liver malignancy, and sarcomatoid hepatocellular carcinoma is a rare malignancy containing both carcinomatous and sarcomatous components.
CASE REPORT
We report a 64-year-old male patient treated with open right trisectionectomy for a 16cm right hemiliver tumour. The diagnosis of sarcomatoid hepatocellular carcinoma was confirmed on histology. Five months after hepatic resection, patient had symptoms suggestive of Horner's syndrome along with left sided shoulder pain, hand weakness, reduced power of the intrinsic hand muscles and reduced pain perception over the C8/T1 dermatome. Magnetic Resonance Imaging (MRI) showed a mass at the left lung apex/superior sulcus involving the left C8, T1 nerve roots, scalene muscles, and brachial plexus. The mass closely abutted the left first rib and partially encased the left subclavian artery. The patient was managed with palliative chemoradiotherapy for Pancoast syndrome.
DISCUSSION
Hepatocellular carcinoma pulmonary metastasis causing Pancoast syndrome is a rare occurrence with only four prior reports, and to the best of our knowledge, pulmonary metastasis from sarcomatoid hepatocellular carcinoma causing Pancoast syndrome is unreported. In this report, we will discuss the clinicopathological characteristics of this case which may provide insight into diagnosis and management of other sarcomatoid hepatocellular carcinoma patients.

Journal of Chiropractic Medicine Dec 2023The purpose of this report was to describe a patient with a Pancoast tumor who presented for chiropractic care with neck and arm pain.
OBJECTIVE
The purpose of this report was to describe a patient with a Pancoast tumor who presented for chiropractic care with neck and arm pain.
CLINICAL FEATURES
A 52-year-old male patient with right-sided cervicothoracic pain and numbness in the right upper extremity presented to a chiropractic office for care. The patient reported an occupational history of repetitive lifting motions and overuse injuries. The patient denied history of smoking at the time of presentation.
INTERVENTION AND OUTCOME
Radiographic imaging revealed tracheal deviation. A chest computed tomography image demonstrated a large lesion in the apex of the right lung, suggestive of bronchogenic carcinoma. The patient was referred to an oncology clinic, where he admitted to having a 20-year history of smoking. The diagnosis of adenocarcinoma was made via biopsy, and the oncologist's evaluation confirmed the cancer to be stage IIIC. The patient received palliative care treatments, as the advanced state of his condition determined that he was not a candidate for surgical intervention.
CONCLUSION
Chiropractors and other first-contact health care providers must keep in mind unusual presentations masquerading as common conditions. This case demonstrates the importance of including apical lung tumors in the differential diagnosis of unilateral arm and neck pain and neurologic deficits of the upper extremity. This case demonstrates the importance of thorough follow-up on images ordered, including the ordering clinicians viewing the images themselves.

We present the case of a 52-year-old male who was recently diagnosed case of a Pancoast tumor and presented to the pulmonary outpatient department with a complaint of pain in the shoulder and chest region which was burning type, associated with shoulder abduction weakness and poor hand grip. Subsequently, he was referred for a -Tc bone scan for metastatic workup, which showed increased uptake in all the joints and long bones of the ipsilateral upper limb. This case highlights the importance of considering nontraumatic cause of pattern similar to complex regional pain syndrome.
