In recent years, there has been a significant global increase in skin cancer incidence, which continues to pose a significant challenge to public health. This retrospective study aimed to comprehensively characterize the epidemiology of histopathologically diagnosed skin cancers at the Department of Dermatology, Jose R. Reyes Memorial Medical Center from January 2013 to December 2022. The research encompassed an analysis of demographic and clinical profiles in 352 cases. The cases consisted of basal cell carcinoma (BCC) (161, 46%), squamous cell carcinoma (SCC) (62, 18%), melanoma (21, 6%), mycosis fungoides (MF) (37, 11%), other cutaneous T-Cell lymphomas (11, 3%), mammary Paget’s disease (7, 2%), extramammary Paget’s disease (6, 1.7%), Langerhans cell histiocytosis (LCH) (8, 2%), sebaceous carcinoma (3, 1%), Merkel cell carcinoma (MCC) (1, 0.3%), dermatofibrosarcoma protuberans (1, 0.3%), angiosarcoma (2, 0.6%), Kaposi sarcoma (3, 0.9%), and cutaneous metastasis (29, 8%). Among the primary cutaneous malignancies, BCC, SCC, MF, and melanoma were the most frequently encountered types. The findings reveal a notable upward trend in all skin cancer incidence, and projections suggest a continued increase in the next five years. BCC and SCC were more common in males and affected predominantly sun-exposed areas, while melanoma exhibited a slight female preponderance and primarily affected the lower extremities (acral melanoma). These skin cancers were more common among elderly individuals. The study highlights the need for standardized documentation to improve data quality on epidemiology. This, in turn, can lead to improved early detection, prevention, and better management of this escalating global public health issue.

OBJECTIVE: To assess the risk of aristolochic acid (AA)-associated cancer in patients with AA nephropathy (AAN). METHODS: A retrospective study was conducted on patients diagnosed with AAN at Peking University First Hospital from January 1997 to December 2014. Long-term surveillance and follow-up data were analyzed to investigate the influence of different factors on the prevalence of cancer. The primary endpoint was the incidence of liver cancer, and the secondary endpoint was the incidence of urinary cancer during 1 year after taking AA-containing medication to 2014. RESULTS: A total of 337 patients diagnosed with AAN were included in this study. From the initiation of taking AA to the termination of follow-up, 39 patients were diagnosed with cancer. No cases of liver cancer were observed throughout the entire follow-up period, with urinary cancer being the predominant type (34/39, 87.17%). Logistic regression analysis showed that age, follow-up period, and diabetes were potential risk factors, however, the dosage of the drug was not significantly associated with urinary cancer. CONCLUSIONS No cases of liver cancer were observed at the end of follow-up. However, a high prevalence of urinary cancer was observed in AAN patients. Establishing a direct causality between AA and HCC is challenging.

OBJECTIVE

To investigate the clinicopathologic profile of testicular cancer at the Southern Philippines Medical Center (SPMC) in Davao City from January 2017 to December 2022.

This is a retrospective study that analyzed data from a cohort of 33 patients using a combination of descriptive statistics and chi-square tests.

The study revealed a mean patient age of 35 years, with the majority (82%) falling between 19 and 59 years. Cryptorchidism was associated with 9% of cases, and most tumors (55%) were located on the right side, with sizes between 3 and 10 cm (58%). The predominant symptom was a painless testicular mass (100%), underscoring the importance of self-examination. Pathologic stage distribution indicates a predominance of advanced stages, notably Stage IIIC at 24%. Germ cell tumors constitute 91% (52% seminoma, 39% non-seminoma), with no significant correlation between tumor stage at diagnosis and number of risk factors identified or body mass index (BMI). Symptom duration trends towards significance in association with advanced stages.

The study contributes to a comprehensive understanding of testicular cancer in the Philippines, aligning with global trends. It emphasizes the crucial role of early detection through selfexamination and timely consultation. The prevalence of advanced stages highlights the imperative for heightened awareness and intervention.

BACKGROUND: Neuroendocrine neoplasms (NENs) are rare tumors characterized by variable biology and delayed diagnosis. However, the nationwide epidemiology of NENs has never been reported in China. We aimed to estimate the incidence and survival statistics of NENs in China, in comparison to those in the United States during the same period. METHODS: Based on the data from 246 population-based cancer registries covering 272.5 million people of China, we calculated age-specific incidence on NENs in 2017 and multiplied by corresponding national population to estimate the nationwide incidence in China. The data of 22 population-based cancer registries were used to estimate the trends of NENs incidence from 2000 to 2017 through the Joinpoint regression model. We used the cohort approach to analyze the 5-year age-standardized relative survival by sex, age group, and urban-rural area between 2008 and 2013, based on data from 176 high-quality cancer registries. We used data from the Surveillance, Epidemiology, and End Results (SEER) 18 program to estimate the comparable incidence and survival of NENs in the United States. RESULTS: The overall age-standardized rate (ASR) of NENs incidence was lower in China (1.14 per 100,000) than in the United States (6.26 per 100,000). The most common primary sites were lungs, pancreas, stomach, and rectum in China. The ASRs of NENs incidence increased by 9.8% and 3.6% per year in China and the United States, respectively. The overall 5-year relative survival in China (36.2%) was lower than in the United States (63.9%). The 5-year relative survival was higher for female patients than male patients, and was higher in urban areas than in rural areas. CONCLUSIONS The disparities in burden of NENs persist across sex, area, age group, and site in China and the United States. These findings may provide a scientific basis on prevention and control of NENs in the two countries.

BACKGROUND: Lung cancer has been the leading cause of cancer-related deaths worldwide for many years. This study aimed to investigate the global patterns and trends of lung cancer. METHODS: Lung cancer incidence and mortality were derived from the GLOBOCAN 2020 database. Continuous data from Cancer Incidence in Five Continents Time Trends were used to analyze the temporal trends from 2000 to 2012 using Joinpoint regression, and average annual percent changes were calculated. The association between the Human Development Index and lung cancer incidence and mortality was assessed by linear regression. RESULTS: An estimated 2.2 million new lung cancer cases and 1.8 million lung cancer-related deaths occurred in 2020. The age-standardized incidence rate (ASIR) ranged from 36.8 per 100,000 in Demark to 5.9 per 100,000 in Mexico. The age-standardized mortality rate (ASMR) varied from 32.8 per 100,000 in Poland to 4.9 per 100,000 in Mexico. Both ASIR and ASMR were approximately twice higher in men than in women. The ASIR of lung cancer showed a downward trend in the United States of America (USA) between 2000 and 2012, and was more prominent in men. The age-specific incidence rates of lung cancer for ages of 50 to 59 years showed an upward trend in China for both men and women. CONCLUSIONS The burden of lung cancer is still unsatisfactory, especially in developing countries like China. Considering the effectiveness of tobacco control and screening in developed countries, such as the USA, there is a need to strengthen health education, accelerate the establishment of tobacco control policies and regulations, and improve early cancer screening awareness to reduce the future burden of lung cancer.

BACKGROUND: Severe liver disease (SLD), including cirrhosis and liver cancer, constitutes a major disease burden in China. We aimed to examine the association of genetic and healthy lifestyle factors with the incidence and prognosis of SLD. METHODS: The study population included 504,009 participants from the prospective China Kadoorie Biobank aged 30-79 years. The individuals were from 10 diverse areas in China without a history of cancer or liver disease at baseline. Cox regression was used to estimate adjusted hazard ratios (HRs) for incident SLD and death after SLD diagnosis associated with healthy lifestyle factors (smoking, alcohol, physical activity, and central adiposity). Additionally, the contribution of genetic risk for hepatitis B virus (HBV, assessed by genetic variants in major histocompatibility complex, class II, DP/DQ [ HLA - DP / DQ ] genes) was also estimated. RESULTS: Compared with those with 0-1 healthy lifestyle factor, participants with 2, 3, and 4 factors had 12% (HR 0.88 [95% confidence interval [CI] 0.85, 0.92]), 26% (HR 0.74 [95%CI: 0.69, 0.79]), and 44% (HR 0.56 [95%CI: 0.48, 0.65]) lower risks of SLD, respectively. Inverse associations were observed among participants with both low and high genetic risks (HR per 1-point increase 0.83 [95%CI: 0.74, 0.94] and 0.91 [95%CI: 0.82, 1.02], respectively; Pinteraction = 0.51), although with a non-significant trend among those with a high genetic risk. Inverse associations were also observed between healthy lifestyle factors and liver biomarkers regardless of the genetic risk. Despite the limited power, healthy lifestyle factors were associated with a lower risk of death after incident SLD among participants with a low genetic risk (HR 0.59 [95%CI: 0.37, 0.96]). CONCLUSIONS Lifestyle modification may be beneficial in terms of lowering the risk of SLD regardless of the genetic risk. Moreover, it is also important for improving the prognosis of SLD in individuals with a low genetic risk. Future studies are warranted to examine the impact of healthy lifestyles on SLD prognosis, particularly among individuals with a high genetic risk.
