Fulltext Resection of large primary chest wall chondrosarcoma with reconstruction: 2 case reports

Wong PS, Tan GP

Med J Malaysia, 2000 Dec;55(4):516-9.

We report two cases of large chest wall primary chondrosarcoma, one of the sternum and the other of the lateral chest wall. Both were treated by radical resection and reconstruction using marlex mesh and methyl methacrylate "sandwich" prosthesis and pedicled latissiumus dorsi flap.

Fulltext Huge Chest Wall Tumour Resection and Reconstruction using Titanium Mesh

Adli Azam MR, Raja Amin RM

Malays J Med Sci, 2015 Jan-Feb;22(1):70-3.

PMID: 25892952 MyJurnal

Malignant chest wall tumour is rare. The presentation is usually aggressive that requires extensive resection to prevent recurrence. However, the extensive resection is to the expense of causing defect on the chest wall and hence, respiratory mechanics. Two cases of chest wall tumour are discussed including the surgical approach of radical tumour resection which was combined with placement of titanium mesh and Tranverse Rectus Abdominis Myocutaneus (TRAM) flap to cover the defect and preserve respiratory mechanical functions. The morbidity of using titanium mesh demonstrated in the case series were infection and injury to surrounding tissue due to its rigidity and large size which required its removal. However the formation of 'pseudopleura' made the thoracic cage return back as closed cavity even after the removal of the titanium mesh and allow normal respiratory functions.

Fulltext Isolated late chest wall recurrence after mastectomy for breast cancer

Azrif M, Saladina JJ, Nani ML, Shahrunniza AS, Norlia A, Rohaizak M

An isolated late chest wall recurrence after mastectomy for breast cancer is rare. We present a case of a lady with a T2N1M0 right breast cancer who developed an isolated local recurrence on the chest wall 11 years after mastectomy. Staging investigations excluded distant metastases. She underwent an excisional biopsy and was started on an aromatase inhibitor. Radiotherapy was given to the chest wall followed by a boost to the site of excision. Although most chest wall recurrences fare poorly, a favourable subgroup can be identified and should be treated aggressively in a multidisciplinary approach.

Verification of tumor dose for patients undergoing external beam radiotherapy is an important part of quality assurance programs in radiation oncology. Among the various methods available, entrance dose in vivo is one reliable method used to verify the tumor dose delivered to a patient. In this work, entrance dose measurements using LiF:Mg;Ti and LiF:Mg;Cu;P thermoluminescent dosimeters (TLDs) without buildup cap was carried out. The TLDs were calibrated at the surface of a water equivalent phantom against the maximum dose, using 6- and 10-MV photon and 9-MeV electron beams. The calibration geometry was such that the TLDs were placed on the surface of the "solid-water" phantom and a calibrated ionization chamber was positioned inside the phantom at calibration depth. The calibrated TLDs were then utilized to measure the entrance dose during the treatment of actual patients. Measurements were also carried out in the same phantom simultaneously to check the stability of the system. The dose measured in the phantom using the TLDs calibrated for entrance dose to 6-and 10-MV photon beams was found to be close to the dose determined by the treatment planning system (TPS) with discrepancies of not more than 4.1% (mean 1.3%). Consequently, the measured entrance dose during dose delivery to the actual patients with a prescribed geometry was found to be compatible with a maximum discrepancy of 5.7% (mean 2.2%) when comparison was made with the dose determined by the TPS. Likewise, the measured entrance dose for electron beams in the phantom and in actual patients using the calibrated TLDs were also found to be close, with maximum discrepancies of 3.2% (mean 2.0%) and 4.8% (mean 2.3%), respectively. Careful implementation of this technique provides vital information with an ability to confidently accept treatment algorithms derived by the TPS or to re-evaluate the parameters when necessary.

Pulmonologist-led ultrasound guided lung biopsy safety and efficacy: a 4-year experience from a tertiary centre in Northern Malaysia

Ismail IN, Alaga A

PMID: 38031216

INTRODUCTION: Ultrasound guided lung biopsy (USLB) is a minimally invasive diagnostic tool with short examination time and real-time monitoring conducted bedside for accurate diagnosis in order to provide the best treatment. However, it is not widely performed by pulmonologists. We aim to explicate the efficacy and safety of USLB led by pulmonologists. The objective of this study is to assess safety and efficacy of USLB performed by pulmonologists in an outpatient setting.

MATERIALS AND METHODS: We retrospectively enrolled patients who underwent the procedure from January 2018 to April 2022. Under real time ultrasound (Hitachi Medical ProSound F37), thoracic lesions adjacent to the chest wall were sampled with a full-core biopsy needle (CT Core Single Action Biopsy Device, 18G × 15 cm, Vigeo, Italy). Chest x-ray was performed 30 minutes post procedure ruling out pneumothorax. Patients were discharged home 1-2 hours post biopsy. Data was analysed using Microsoft Excel 2010 and Statistical Package for Social Science (SPSS) Version 26.

RESULTS: A total of 18 patients (14 males, 4 females) underwent USLB for lung tumours. Biopsies were histologically deemed adequate with an overall diagnostic yield of 77.8% (14/18). A total of 57% were positive for thoracic malignancy (21% squamous cell carcinoma, 21% adenocarcinoma, 15% small cell carcinoma) and another 43% were positive for extra thoracic malignancy (1 hepatocellular carcinoma, 2 DLBCL, 1 Hodgkin's lymphoma, 1 seminoma, 1 thymoma). Four patients had inconclusive results but managed to get positive results from surgical or lymph node biopsy (thymoma and adenocarcinoma). Statistical analysis showed more than two passes are needed to achieve a positive HPE yield (p value<0.05). There were nil complications to all the cases done.

CONCLUSIONS: USLB can safely and effectively be performed by trained pulmonologists with excellent accuracy and low complication rate in outpatients.
