Summary
Pancoast tumours, a rare lung cancer subtype, often present with delayed diagnosis due to symptoms mimicking musculoskeletal issues. Early chemo-radiotherapy followed by surgery improves survival outcomes for these challenging cases.
Area of Science:
- Oncology
- Thoracic Surgery
Background:
- Pancoast tumours are infrequent lung cancers often presenting with delayed diagnosis.
- Symptoms like arm pain and tingling can be misattributed to musculoskeletal conditions.
Observation:
- A 63-year-old male presented with chest pain and arm symptoms, initially normal ECG and blood work.
- Imaging revealed a 6 cm superior sulcus tumour involving the upper ribs; biopsy confirmed non-small cell lung carcinoma.
- The patient received induction chemotherapy and radiotherapy followed by right upper lobectomy.
Findings:
- The patient survived 1 year post-surgery with no evidence of disease recurrence or metastasis.
- Tri-modal therapy (chemo-radiotherapy then surgery) demonstrated efficacy.
Implications:
- Highlights the importance of considering Pancoast tumours in patients with persistent arm and shoulder pain.
- Pre-operative chemoradiotherapy shows improved survival compared to radiotherapy alone for Pancoast tumours.
- Timely diagnosis and multimodal treatment are crucial for improving outcomes in Pancoast tumour patients.

01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:26Peripheral Artery Disease IV: Nursing Management
The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
