Background:
s/Aims: The treatment landscape for hepatocellular carcinoma (HCC) has significantly evolved over the past decade. We aimed to analyze trends in treatment patterns for HCC using a nationwide claims database from the Korean Health Insurance Review and Assessment Service.
Methods:
This retrospective population-based cohort study analyzed 171,002 newly diagnosed HCC patients between 2008 and 2022. Etiologies and treatment modalities were categorized based on the ICD-10 codes and insurance data.
Results:
The annual incidence decreased from 11,814 in 2008 to 10,443 in 2022. However, patients aged ≥70 increased noticeably, with those aged ≥80 rising from 3.8% in 2008 to 13.1% in 2022. From 2008 to 2022, the predominant cause of hepatitis B virus decreased from 68.9% to 59.7%, whereas nonalcoholic fatty liver disease increased from 8.9% to 15.8%. The initial treatment trends shifted: surgical resection and systemic therapy increased from 12.2% to 21.3% and from 0.2% to 9.6%, whereas transarterial therapy decreased from 49.9% to 36.6%. Best supportive care decreased from 31.7% to 21.3%. In the subgroup analysis, laparoscopic resection rate increased from 10.6% to 60.6% among the surgical resections. Sorafenib initially accounted for 100%, lenvatinib peaked at 36.5% in 2021, and atezolizumab-bevacizumab became the most widely used (63.1%) by 2022 among the systemic therapies.
Conclusions
This study demonstrates the temporal changes in the treatment patterns of Korean HCC patients. Surgical resection, particularly laparoscopic liver resection, and systemic therapy has increased significantly. These changes may have been influenced by reimbursement policies and advances in clinical research.

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the most common form of primary extranodal lymphomas. In most cases, it is developed as multifocal and mucosal lesions, and its initial diagnosis is made by biopsy of suspicious lesions on endoscopy. However, when gastric MALT lymphoma afflict submucosal site without typical mucosal lesion, further procedures are necessary for diagnosis, such as endoscopic mucosal resection and endoscopic ultrasonography. We recently experienced two cases of submucosal tumor-like gastric MALT lymphoma. Both cases were without any mucosal lesion. One case was confirmed by endoscopic mucosal resection, and the latter was by wedge resection. Treatment modalities included endoscopic mucosal resection, surgery, H. pylori eradication, and/or chemotherapy. Both cases achieved complete remission until our 18 months' and 16 months' follow up.

Metastases to the thyroid gland are not frequently observed in clinical practice, although an overall incidence of secondary thyroid malignant tumors has been reported to range from 1.25% to 24% in autopsy series. Generally, patients with metastatic thyroid cancer present with euthyroidism and they do not develop thyroid dysfunction. Thyroid dysfunctions, including hypothyroidism and hyperthyroidism, rarely occur in patients with metastatic thyroid cancer. We describe here a case of hypothyroidism induced by thyroid metastasis from cancer of an unknown primary site in a 53-year-old man and another case of thyrotoxicosis induced by thyroid metastasis from lung cancer in a 65-year-old man.

Circumscribed palmar or plantar hypokeratosis is a rare dermatosis, and it consists of asymptomatic erythematous, well-circumscribed and depressed patch with scaly borders on the palm or sole. It usually affects middle-aged or elderly women. Histopathologically, it has a sharp stair between the normal and involved skin, and a demarcated area with an abrupt decrease in the horny layer thickness. We report herein a case of circumscribed palmar hypokeratosis that was successfully treated with cryotherapy.

Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. All ethnicities can be affected, but TPP typically presents in men of Asian descent. The most common cause of TPP in thyrotoxicosis is Graves' disease. However, TPP can occur with any form of thyrotoxicosis. Up to our knowledge, very few cases ever reported the relationship between TPP and painless thyroiditis. We herein report a 25-yr-old Korean man who suffered from flaccid paralysis of the lower extremities and numbness of hands. The patient was subsequently diagnosed as having TPP associated with transient thyrotoxicosis due to painless thyroiditis. The paralytic attack did not recur after improving the thyroid function. Therefore, it is necessary that early diagnosis of TPP due to transient thyrotoxicosis is made to administer definite treatment and prevent recurrent paralysis.

Carney complex is an autosomal dominant syndrome characterized by multiple neoplasias, including myxomas and endocrine tumors, spotty pigmentation, and schwannomas. Primary pigmented nodular adrenal dysplasia (PPNAD) is a cause of Cushing syndrome, independently of adrenocorticotropic hormone. A 21-year-old man was referred for evaluation with multiple spinal compression fractures and adenomas affecting both adrenal glands. Plasma and urinary cortisol levels were elevated and were not suppressed by the administration of a high dose of dexamethasone. The patient was diagnosed with Carney complex manifesting as Cushing syndrome due to PPNAD with multiple pigmented skin lesions. Left adrenalectomy was performed because the nodule on the left adrenal gland was markedly larger than the other nodules. Subsequently, right adrenalectomy was also performed. Pathological analysis revealed that the adrenal glands contained multiple dark brown and black nodules. We describe herein our recent experience of a case of Carney complex manifesting as Cushing syndrome due to PPNAD, with lentigines on the lips, and review the published literature on this subject.

BACKGROUND: Whether thyroid lobectomy alone is a sufficient treatment for papillary thyroid microcarcinoma (PTMC) remains controversial. The aim of this study is to evaluate the predictive factors for incidental contralateral carcinoma in patients confirmed of unilateral PTMC preoperatively. METHODS: Between January 2007 and December 2009, 393 patients underwent thyroid surgery for unifocal and unilateral PTMC preoperatively at Pusan National University Hospital. A total thyroidectomy with central neck dissection was routinely performed for these patients during this study period. RESULTS: Among the 393 cases in the cohort, 77 patients (19.6%) had incidental PTMC in the contralateral lobe. In patients with incidental contralateral carcinoma, there was higher prevalence in extrathyroid extension, occult ipsilateral carcinoma, pathologic Hashimoto's thyroiditis, and central lymph node metastasis compared to those without contralateral carcinoma. The mean tumor size also increased in patients with contralateral carcinoma. Multivariate logistic regression showed that extrathyroid extension (P = 0.049), occult ipsilateral carcinoma (P < 0.001), pathologic Hashimoto's thyroiditis (P = 0.038), and central lymph node metastasis (P = 0.002) were predictive factors for incidental contralateral carcinoma. CONCLUSION: In conclusion, multifocality in the ipsilateral lobe, central lymph node metastasis, extrathyroid extension, and Hashimoto's thyroiditis is associated with the presence of contralateral carcinoma. Thus, if these factors are found by preoperative and/or postoperative evaluation, total thyroidectomy or completion thyroidectomy is necessary for the treatment of PTMC.
