Surgery for a symptomatic massive liver haemangioma

Liver haemangiomas are the most common benign hepatic tumours, but secondary portal hypertension resulting from haemangiomas is exceedingly uncommon. We present a case of a man in his 50s who presented with a progressively enlarging mass in the right upper abdomen. CT of the liver revealed a large hypodense lesion involving the right lobe, with two smaller lesions in the left lobe. The portal vein was compressed by the tumour, causing portal hypertension. The patient underwent right hepatectomy. Postoperatively, the patient had an uneventful course, and a 3-month follow-up demonstrated resolution of the oesophageal varices, portal gastropathy, with hypertrophy of the left lobe. This case report highlights the successful surgical management of a rare massive hepatic haemangioma causing portal hypertension with surgical resection, emphasising the potential benefits of surgical intervention with minimal complications.

Impact of Neoadjuvant Concurrent Chemoradiation (NACCRT) on Operability and Survival in Locally Advanced Inoperable Breast Cancer

PURPOSE/OBJECTIVE(S)

Inoperable locally advanced breast cancers (LABC) are treated with neoadjuvant chemotherapy (NACT). However, many patients remain inoperable after NACT due to an inadequate response. We, therefore, investigated the role of neoadjuvant concurrent chemoradiation (NACCRT) in this setting.

MATERIALS/METHODS

Patients with inoperable Stage III LABC were prospectively recruited in the study between May 2017 and December 2021. NACT consisted of 4 cycles of q3weekly Adriamycin (60 mg/m2) and Cyclophosphamide (600mg/m2), and 4 cycles of q3weekly Paclitaxel (175 mg/m2). Concurrent radiotherapy with 6 MV X-rays was given using a 3D conformal technique to a total dose of 46 Gy (2 Gy/fraction, 5 days/week) to the involved breast, axilla, supraclavicular fossa, and internal mammary chain (upper 3 intercostal spaces) along with the first two cycles of paclitaxel. A 0.5 cm bolus was used to boost the skin till the appearance of hyperpigmentation. All patients were assessed for surgery after the completion of the planned neoadjuvant treatment. Adjuvant treatments were given based on the receptor status. The impact of neoadjuvant CTRT on the pathological complete response (pCR), operability, and survival was analyzed. Event-free survival (EFS) and Overall Survival (OS) were analyzed using the Kaplan-Meier method.

RESULTS

The study enrolled 202 female patients with a median age of 52 years, with 23.7% having IIIA, 65.3% IIIB, and 10.8% having IIIC disease. Hormone-receptor (HR) positive disease was observed in 90/202 (44.6%) patients, triple-negative (TNBC) in 50/202 (24.8%) and Her2/neu positive in 62/202 (30.7%) patients. Modified radical mastectomy was performed in 88.1% of patients, with 8.5% remaining inoperable and 3.4% declining surgery due to clinical complete response (cCR). Among the patients who underwent MRM, 65/178 (32.2%) patients had a pCR. pCR was observed in 13/81 (16%) with HR-positive disease, 21/46 (45.6%) with TNBC, and 31/51 (60.7%) patients with Her2/neu-positive disease. Grade 3 skin reactions were observed in 39/202 (19.3%). Postoperative wound morbidity requiring hospitalization was observed in 19/178 (10.6%) patients. The median follow-up was 42 months, with 4-year EFS and OS of 63.8% and 71.5%, respectively. Six out of 7 patients who were in cCR and declined surgery are alive and remain in cCR. On subgroup analysis of Her 2 positive patients, pCR was significantly associated with improved EFS and OS (89.8% vs 33.3%, p = 0.001 and 89.1% vs 44.4%, p = 0.001 respectively).

CONCLUSION

Our study demonstrates the feasibility and efficacy of NACCRT in improving operability, pCR rates and survival outcomes in patients with inoperable LABC. The results suggest that NACCRT can be considered for use in clinical practice with careful patient selection. These findings contribute to the ongoing efforts to optimize treatment for this patient population and warrant further investigation in larger, randomized trials.

Updated emm-typing protocol for Streptococcus pyogenes

OBJECTIVES

PCR-based typing of the emm gene Streptococcus pyogenes often results in the amplification of multiple bands. This has resulted in the misclassification of strains into types based on non-emm gene sequences. We aimed to improve the specificity of the emm typing PCR reaction using a primer called CDC3, the sequence for which has been previously used to identify emm genes in silico.

METHODS

The proposed primer CDC3 was validated in silico from a global database of 1688 GAS genomes and in vitro with 32 isolates. PCR reactions were performed on genomic DNA from each isolate, using the published CDC1 forward primer with the CDC2 reverse primer or the new CDC3 reverse primer. The products were examined by gel electrophoresis, and representative PCR products were sequenced.

RESULTS

In 1688 S. pyogenes genomes, the previous CDC2 reverse primer annealed in silico in 1671 emm genes and also in 2109 non emm genes in close proximity, whereas the new CDC3 primer annealed in 1669 emm genes only. The remaining 19 genes without a CDC3 binding site were chimeric emm genes. The PCR pair CDC1+CDC3 produced a single band at appropriate molecular weight in all 32 isolates tested, while the CDC1+CDC2 pair produced more than one band in 13 of 32 isolates (40%).

CONCLUSIONS

The new CDC3 primer is more specific for emm genes than the previous CDC2 primer and represents a simple solution to reduce the potential for mistyping S. pyogenes strains.

Partial encephalocraniocutaneous lipomatosis syndrome

Encephalocranial lipomatosis is a rare disorder that characteristically involves ectomesodermal tissues such as skin, eye, and the central nervous system. Here, we report a 3-year-old girl presented with developmental delay, seizures, limbal dermoid, and weakness of right lower limb. Imaging revealed hemiatrophy, arachnoid cyst, and polymicrogyria. The constellation of clinical finding and imaging leads to the diagnosis.
