Beyond clinical trials: real-world impact of immunotherapy on NSCLC in Jordan.

Background: This study aims to evaluate real-world (rw) outcomes of immunotherapy (IO) for advanced stage NSCLC at King Hussein Cancer Center (KHCC) in Jordan. Methods: Advanced stage NSCLC patients who received IO at KHCC between 2017 and 2022 were included. The data were retrospectively collected. PFS and OS were estimated for patients with ECOG performance status (ECOG PS) 0-1. Cox regression analyzed predictors of OS in first-line (1L) IO, regardless of performance status. Results: The total number of patients included was 244. Out of those, 160 (65%), 67 (28%), and 17 (7%) patients received IO as 1L, second-line (2L), or third-line or beyond (3L or beyond), respectively. The median age for all patients was 59 years. Male were 88%, and 77% were smokers. The median follow-up time was 12.5 months. The median PFS and OS for 1L IO were 7 [95% CI 5.8 - 10.3] and 11.8 [95% CI 8.8 - 14.4], months, respectively. In the first 3 months after starting 1L IO, 34/160 (21%) patients had died. For those who survived beyond 3 months after starting 1L IO, the median PFS and OS were 11.3 [95% CI 8.3 - 16.5] and 15.4 [95% CI 13.2 - 21] months, respectively. In the Cox regression model of 1L IO patients with any performance status, ECOG PS 2 was predictive of worse OS compared to ECOG PS 0-1 (p= 0.005). Conclusion: This real-world study of advanced-stage NSCLC patients treated with immunotherapy at KHCC reveals outcomes that fall short of those anticipated from clinical trials. The inclusion of Middle Eastern patients in lung cancer trials is essential to ensure adequate representation of various ethnicities in clinical research.

Metastatic esophageal carcinoma to the eye masquerading as inflammatory vitreo-retinitis: A case report and literature review.

We report an unusual case of metastatic esophageal carcinoma to the vitreous associated with focal retinitis in a 44-year-old male. A 44-year-old male patient, known case of locally advanced esophageal carcinoma, presented with a 3-day history of left eye floaters. The initial diagnosis was inflammatory vitreo-retinitis that responded to systemic steroids. Four months later, the patient presented with relapsed intraocular inflammation, vitreous biopsy using a 25G needle was performed, and cytology confirmed the presence of metastatic carcinoma consistent with his primary esophageal cancer. The patient received external beam radiotherapy to his ocular and brain metastasis, and his eye examination was stable. Five months later, the patient passed away due to progressive brain metastasis.

Transdiaphragmatic single-port video-assisted thoracoscopic surgery; a novel approach for pulmonary metastasectomy through laparotomy incision - case series.

BACKGROUND: Pulmonary metastasectomy was performed in the early twentieth century and ever since, it has evolved to be one of the main treatment options for certain metastatic malignancies. The advancement of minimally invasive procedures enabled new techniques to minimize morbidity and improve patient quality of care and overall outcome. CASES PRESENTATION: Herein we present three patients, aged 53, 48, and 27 years, known to have sigmoid, rectal, and non-seminomatous germ cell tumors respectively. All patients were diagnosed to have metastatic lung nodules and underwent laparotomy to excise abdominal tumors followed by trans-diaphragmatic single-port video-assisted thoracoscopic pulmonary metastasectomy. All patients achieved complete surgical tumor excision, and none had pulmonary related complications on follow-up. CONCLUSION: Our prescribed novel trans-diaphragmatic single-port video-assisted thoracoscopic surgery (VATS) technique for synchronous pulmonary metastasectomy and intra-abdominal tumor resection is safe and can achieve complete resection with negative margins.

Heart rupture repair during huge mediastinal mass resection - case report.

BACKGROUND: Ventricular rupture is rarely described in the literature outside the context of myocardial infarction, infection or neoplasm. It is associated with a high mortality rate due to late presentation and delayed surgical intervention, which involves sutureless or sutured techniques. Comprehensive literature review failed to identify any case of intra-operative right ventricular heart rupture followed by myocardial repair and a complete recovery after a prolonged intensive care unit (ICU) stay. CASE PRESENTATION: A 57-year-old previously healthy gentleman presented complaining of a new onset shortness of breath for 2 months. A large mediastinal mass was found on chest imaging and biopsy revealed a thymoma. Patient received a neoadjuvant Cisplatin/Doxorubicin/Cyclophosphamide (CAP) regimen chemotherapy then sternotomy and thymectomy en bloc with anterior pericardium. Post-thymectomy, the patient continued to be hypotensive in recovery despite aggressive fluid resuscitation. He was sent back to theatre, aggressive fluid resuscitation continued, surgical site exploration was done by reopening the sternum, and the bleeding source was identified and controlled, but intraoperative asystole developed. During internal cardiac massage, the right ventricle ruptured with a 3 cm defect which was successfully repaired using a pericardial patch without a bypass machine due to unavailability at our cancer center. The patient remained dependent on mechanical ventilation through tracheostomy for a total of 2 months due to bilateral phrenic nerve paralysis, was discharged from ICU to the surgical floor 66 days after the operation and weaned off ventilator support after 85 days, adequate respiratory and physical rehabilitation followed. Patient is doing very well now with excellent performance, and free of tumor recurrence 30 months after surgery. CONCLUSION: Right ventricular rupture is rarely described outside the context of myocardial infarction and valvular heart disease. Tumor proximity to the heart and neoadjuvant cardiotoxic chemotherapy are the proposed causes for precipitating the cardiac rupture in our case. Post-surgical patients who receive early physical rehabilitation and respiratory physiotherapy have improved survival and outcome.

Diagnosis of mesenteric panniculitis in the multi-detector computed tomography era. Association with malignancy and surgical history.

OBJECTIVES: To assess the prevalence and associations of mesenteric panniculitis (MP) using multi-detector CT (MDCT). METHODS: This retrospective study included 4758 consecutive patients who underwent abdomino-pelvic MDCT between January 2012 and December 2014 at Jordan University Hospital, Amman, Jordan. Radiological database was searched for MP diagnosis and patients with suspected MP were re-evaluated by an experienced radiologist to confirm the diagnosis. Data on all patients with confirmed MP diagnosis were subsequently collected and analyzed. RESULTS: Computed tomography features of MP were identified in 90 patients (41 males, 49 females), a prevalence of 1.9%. Mesenteric panniculitis was identified in both asymptomatic and symptomatic patients. Malignancy was found in 28 MP patients (31%) and 44 of the MP patients (49%) had prior history of abdomino-pelvic surgery. Mesenteric panniculitis was significantly more frequently associated with prior abdomino-pelvic surgery (p=0.0001) and the likelihood of associated malignancy in patients with MP was 2.1-fold higher than in patients without MP (p=0.0013). Conclusion: Mesenteric panniculitis can be reliably diagnosed by MDCT due to its typical CT appearance. Its identification is important because of its significant association with malignancy and because it represents one of the differential diagnoses in patients with nonspecific symptoms referred for abdomino-pelvic CT.
