Pancoast tumor: a modern perspective on an old problem

Deciphering the enigmatic symptoms of Pancoast tumors: Navigating the complex landscape of pain management-A case report

Pancoast tumors, also known as superior sulcus tumors, encompass a diverse spectrum of neoplasms that infiltrate the apex of the chest wall, yielding distinctive clinical presentations. One of the earliest signs of tumor growth is pain radiating to the upper limb, stemming from peripheral nerve involvement, which can mimic joint pain or spinal radicular irritation. In this case report, we present the clinical history of a 64-year-old female smoker who had previously been recommended for orthopedic elbow surgery due to epicondylitis. Subsequent to the development of additional symptoms and rigorous investigation, a Pancoast tumor was diagnosed. Furthermore, we discuss the characteristic treatment modalities available for Pancoast tumors, including pharmacological pain management and interventional strategies such as spinal cordotomy and spinal alcoholysis. This case underscores the significance of recognizing atypical presentations and emphasizes the importance of comprehensive evaluation in the diagnosis and management of Pancoast tumors.

Pancoast Tumor With Cardiac Metastases and Intracardiac Thrombosis

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.

Management of Lung Cancer Invading the Superior Sulcus

Superior sulcus tumors have posed a formidable therapeutic challenge since their original description by Pancoast and Tobias in the early twentieth century. Initial therapeutic efforts with radiotherapy were associated with high rates of relapse and mortality. Bimodality therapy with complete surgical resection in the 1960s paved the way for trimodality therapy as the current standard of care in the treatment of superior sulcus tumors. The evolution of treatment approaches over time has provided outcomes that come increasingly closer to rivaling those of similarly staged nonapical lung cancer.

Using the Malthus programme to predict the recruitment of patients to MR-linac research trials in prostate and lung cancer

In this study, we used evidence-based mathematical modelling to predict the patient cohort for MR-linac to assess its feasibility in a time of austerity. We discuss our results and the implications of evidence-based radiotherapy demand modelling tools such as Malthus on the implementation of new technology and value-based healthcare.

Single Posterior Approach for En-Bloc Resection and Stabilization for Locally Advanced Pancoast Tumors Involving the Spine: Single Centre Experience

STUDY DESIGN

Monocentric prospective study.

PURPOSE

To assess the safety and effectiveness of the posterior approach for resection of advanced Pancoast tumors.

OVERVIEW OF LITERATURE

In patients with advanced Pancoast tumors invading the spine, most surgical teams consider the combined approach to be necessary for "en-bloc" resection to control visceral, vascular, and neurological structures. We report our preliminary experience with a single-stage posterior approach.

METHODS

We included all patients who underwent posterior en-bloc resection of advanced Pancoast tumors invading the spine in our institution between January 2014 and May 2015. All patients had locally advanced tumors without N2 nodes or distant metastases. All patients, except 1, benefited from induction treatment consisting of a combination of concomitant chemotherapy (cisplatin-VP16) and radiation.

RESULTS

Five patients were included in this study. There were 2 men and 3 women with a mean age of 55 years (range, 46-61 years). The tumor involved 2 adjacent levels in 1 patient, 3 levels in 1 patient, and 4 levels in 3 patients. There were no intraoperative complications. The mean operative time was 9 hours (range, 8-12 hours), and the mean estimated blood loss was 3.2 L (range, 1.5-7 L). No patient had a worsened neurological condition at discharge. Four complications occurred in 4 patients. Three complications required reoperation and none was lethal. The mean follow-up was 15.5 months (range, 9-24 months). Four patients harbored microscopically negative margins (R0 resection) and remained disease free. One patient harbored a microscopically positive margin (R1 resection) and exhibited local recurrence at 8 months following radiation treatment.

CONCLUSIONS

The posterior approach was a valuable option that avoided the need for a second-stage operation. Induction chemoradiation is highly suitable for limiting the risk of local recurrence.

Palliative sequential chemoradiotherapy for pulmonary sulcus tumor: A case report

Pulmonary sulcus tumors are occasionally encountered in non-small-cell lung cancer (NSCLC) patients. If the patients have a good clinical condition, concurrent chemoradiotherapy is indicated. However, palliative chemotherapy and chemoradiotherapy for patients exhibiting a poor overall condition have not been reported to date. We herein report the case of a 54-year-old female patient with a pulmonary sulcus tumor, who had a poor performance status. The patient received sequential chemoradiotherapy, with no severe complications. There was no local recurrence until the time of death, 8 months after the initiation of therapy. Palliative sequential chemoradiotherapy for pulmonary sulcus NSCLC must be effective and carry low risk of complications. Palliative sequential chemoradiotherapy may be considered in certain patients with pulmonary sulcus NSCLC. Either chemotherapy or radiotherapy is administered first and, if there is no apparent deterioration of the patient's general condition, the next treatment modality is administered.

Resection of the First Rib With Preservation of the T1 Nerve Root in Pancoast Tumors of the Lung

BACKGROUND

Surgical outcomes for Pancoast (superior sulcus) tumors of the lung have significantly changed during the last few decades and have improved with use of curative-intent surgery by utilizing en bloc complete resections.

METHODS

A retrospective analysis was conducted of 11 selected patients treated at Moffitt Cancer Center from 2007 to 2016. Data from patient records were collected and analyzed.

RESULTS

All 11 patients with a Pancoast tumor involving the first rib had their T1 root preserved at surgery. In 10 patients (90.9%), the tumor was removed en bloc. Clear margins of resection were documented in 4 cases (36.0%). No patient developed postoperative hand weakness, but 3 patients (27.3%) had minor postoperative complications, including air leak, chylothorax, and pericardial effusion. One iatrogenic injury to the subclavian artery was reported during surgery; the injury was subsequently repaired. No operative mortality was reported.

CONCLUSIONS

Radical resection of Pancoast tumors is considered to be safe, and preserving the T1 nerve root provides more favorable, functional outcomes.
