A Pancoast or superior sulcus tumor is a rare, bronchogenic carcinoma. In the early period, shoulder pain is the most common symptom. In this case, the patient had presented with complaints of shoulder and arm pain at other outpatient clinics and was examined primarily for musculoskeletal causes and radiculopathy. The patient had no complaints of facial symptoms and Horner's syndrome signs, such as anhidrosis of the face and neck region, were not noticed. Advanced imaging of a patient with preganglionic Horner's syndrome is important. Fewer than 50% of patients with a Pancoast tumor have a resectable lesion at the first diagnosis. Diagnosis is often delayed or there may be a misdiagnosis because musculoskeletal disorders are the focus and there are few lung-related complaints. A detailed examination and anamnesis is very important in patients with arm and shoulder pain.

INTRODUCTION
Superior sulcus tumors (SSTs) are a wide range of tumors invading a section of the apical chest wall called the thoracic inlet. The unique characteristics of SSTs lie in the anatomy of the region where these tumors occur. For this reason, a surgical approach to treating these tumors is technically demanding, and complete resection may be difficult to accomplish.
CASE PRESENTATION
A 71-year-old Japanese man presented at our hospital due to left anterior chest pain and an abnormal chest CT scan showing a 40 × 33 × 30-mm tumor located in the left anterior apex of the thoracic inlet. This tumor had invaded the first and second rib and was located near the subclavian vein. There was no significant distant metastasis. Therefore, we performed surgical resection. The surgical procedure included three steps. First, we performed VATS observation via the left thoracic cavity. Second, via the transmanubrial approach, we obtained tumor-free margins of the anterior cervical structures. Third, through VATS in the left lateral decubitus position, we performed left upper lobectomy and mediastinal lymph node dissection. This surgery was successful, with no postoperative complications.
DISUCUSSION
This surgical approach was effective and safe for treating a superior sulcus tumor located the anterior apex of the thoracic inlet. Next, VATS lobectomy is minimally invasive and safe after the transmanubrial approach for managing anterior superior sulcus tumor.
CONCLUSION
We experienced a case of locally advanced superior sulcus tumor located at the anterior apex of the thoracic inlet and performed complete resection.

Pancoast tumors are non-small cell lung tumors, which can invade the ribs, vertebrae, sympathetic ganglia and brachial plexus. In this study, a patient with right-sided Pancoast tumor presented with intractable chronic pain on the right neck, upper extremity and chest wall. The chronic pain associated with Pancoast tumor, which was difficult to treat with opioids and other medications, was effectively treated with a high-thoracic erector spinae plane block (ESPB). Prolonged analgesia was provided with an ESP catheter to wean the patient from opioids. This case report provides an example where the novel interfacial ESP block can provide pain relief in challenging situations such as lung malignancies involving deeper structures and extensive areas of pain.

A 74-year-old man presented to an orthopedic spine surgeon with signs and symptoms consistent with cervical radiculopathy. Investigation revealed metastasis of a Pancoast tumor to the patient's brachial plexus. A year after initial diagnosis, the patient achieved full neurological function of his left arm. Pancoast tumors are rare in the orthopedic population. Thorough physical examination, imaging, and nerve conduction studies ultimately led to the patient's diagnosis.

BACKGROUND
Metastatic carcinomas to the upper jaw region are very rare and unfortunately occur in advanced stages of malignancies. Pancoast tumor is a challenging subset of lung carcinoma commonly followed by distant metastasis. Since the metastatic lesion of our patient was very huge and unusual, we decided to report the case.
CASE PRESENTATION
Our patient was a middle-aged heavy smoker male with a history of unresectable pancoast tumor. He was referred to the dental clinic with an expanded maxillary metastasis involving the bone and sinus region as well as oral soft tissues. To confirm the primary site of his malignancy, immunohistochemical staining was performed.
CONCLUSION
Distant metastases of a pancoast tumor are more frequent when the primary tumor is unoperable and bone involvement is one of the early manifestations of disease.

Review
BACKGROUND
Pancoast's syndrome is caused by malignant neoplasm of superior sulcus of the lung which produces destructive lesions of thoracic inlet and comes along with the involvement of brachial plexus and stellate ganglion. Computed tomography (CT) or magnetic resonance imaging (MRI) scans can detect early lesions otherwise missed by routine radiographs and can also define the local extent or metastatic progression of the disease. Protocols involving combinations of irradiation, chemotherapy, and surgery are currently being under investigation to determine the best management.
AIMS
This work reviewed the current diagnostic and therapeutic approaches to Pancoast's tumors.
DISCUSSION
Patients with lung superior sulcus carcinoma should be considered for surgery only after an appropriate diagnostic assessment. The perfect candidate for surgery should have a confined to the chest disease with T3N0M0 staging. Inoperable patient with severe pain after irradiation therapy may benefit from palliative surgical resection. Medical therapy plays only a secondary role in lung cancers, patients with disseminated lung cancer might require palliative treatment and medical management of paraneoplastic syndrome symptoms. Following surgery, radiation and chemotherapy may improve local and systemic control by addressing individual adverse findings.
CONCLUSIONS
The cooperation of surgeons, clinicians and radiologists represents the gold standard today and a multidisciplinary approach is essential to achieve the best outcome possible. Further studies are advisable in order to define the best surgical approach and the real advantage of mini-invasive surgery by comparison with open surgery.

Review
The tumor, node, metastasis (TNM) staging system approved by International Association for the Study of Lung Cancer (IASLC) and the American Joint Committee on Cancer (AJCC) to stage lung cancer was recently revised. The latest revision is the 8th edition published in January, 2017. This new edition made some important changes to the previous edition, including modification of the T classification based on 1 cm increment, downstage of T descriptor including endobronchial tumor disregarding its distance from carina (T2), merging total and partial atelectasis/pneumonitis into the same T category (T2), upstage diaphragmatic invasion to T4, new classification concept of adenocarcinoma in situ and minimally invasive adenocarcinoma for pure and part-solid ground-glass nodules, and further division of extrathoracic metastasis into M1b and M1c based on the number and sites of extrathoracic metastases. Consensus is reached for debating situations not covered in the previous edition of staging system, such as the classification of pancoast tumor based on its invasion depth and staging tumors that extend directly across the fissure as T2a. Classification of multiple sites of pulmonary involvement, including multiple primary lung cancer, separate lung cancer nodules, multiple ground-glass or lepidic lesions, and consolidation, is also discussed. Even though the 8th edition of the TNM lung staging system provides us with more precise classification based on prognostic analysis of each TNM descriptors, there are still some potential limitations and clinical situations that have not yet been clarified in terms of clinical staging by imaging. It is important for radiologists to understand the major changes introduced in the 8th edition of TNM staging and to recognize the potential pitfalls and limitations of imaging interpretation to precisely classify the clinical stage of lung cancer.

INTRODUCTION
Target delineation variability is a significant technical impediment in multi-institutional trials which employ intensity modulated radiotherapy (IMRT), as there is a real potential for clinically meaningful variances that can impact the outcomes in clinical trials. The goal of this study is to determine the variability of target delineation among participants from different institutions as part of Southwest Oncology Group (SWOG) Radiotherapy Committee's multi-institutional quality assurance study in patients with Pancoast tumors as a "dry run" for trial implementation.
METHODS
CT simulation scans were acquired from four patients with Pancoast tumor. Two patients had simulation 4D-CT and FDG-FDG PET-CT while two patients had 3D-CT and FDG-FDG PET-CT. Seventeen SWOG-affiliated physicians independently delineated target volumes defined as gross primary and nodal tumor volumes (GTV_P & GTV_N), clinical target volume (CTV), and planning target volume (PTV).Six board-certified thoracic radiation oncologists were designated as the 'Experts' for this study. Their delineations were used to create a simultaneous truth and performance level estimation (STAPLE) contours using ADMIRE software (Elekta AB, Sweden 2017). Individual participants' contours were then compared with Experts' STAPLE contours.
RESULTS
When compared to the Experts' STAPLE, GTV_P had the best agreement among all participants, while GTV_N showed the lowest agreement among all participants. There were no statistically significant differences in all studied parameters for all TVs for cases with 4D-CT versus cases with 3D-CT simulation scans.
CONCLUSIONS
High degree of inter-observer variation was noted for all target volume except for GTV_P, unveiling potentials for protocol modification for subsequent clinically meaningful improvement in target definition. Various similarity indices exist that can be used to guide multi-institutional radiotherapy delineation QA credentialing.
