The most common age group was 50-59 that covered more than a quarter patients (26.8%). Malignant of male genital organs, urinary tract made up the highest percentage in advanced age groups (60-79) whereas malignant of breast, thyroid and other endocrine glands recorded the highest figure in the younger one (40-49).

In terms of regions

Figure 3. Distribution of the 5 most common cancers by geographic regions

In the coastal areas, stomach cancer accounted for the highest percentage (20.1%). In rural and urban areas, lung cancer constituted the largest proportion (18.9% and 17.0% respectively). In mountainous areas, liver cancer overtook lung cancer to register the highest figure out of all categories surveyed (18.9%).

General characteristics of the cancer patients

Out of the total 2,008 cancer cases, the mean age of cancer patients was 58.3± 14.9 years. Among them, the smallest was 7 and the largest was 98. The most common age group of cancer was 50-59 years (26.8%), followed by the 60-69 age group (22.7%). With regards to gender, the male to female ratio was 1.2:1. Cancer patient’s occupational profiles were varied, with the majority belonging to tired/aged group (41.5%), followed by farmer/worker (32.8%); other occupations made up lower figures. 72.4% of cancer patients resided in Thua Thien Hue province.

Figure 4. Number of cancer cases by year and sex from 2008 to 2018

From 2008 to 2018, there was a significant increase in the number of newly diagnosed and treated cancer cases at Hue University Hospital Medical.

Figure 5. Number of cancer cases by age and sex from 2008 to 2018

In the age groups under 50 years, the number of female cases was higher than that of males and reverse trend was observed in the remaining age categories.

Basis Diagnosis

Table 3. Basis Diagnosis

Basis Diagnosis	Frequency	Percentage
Histology/ Cytology	1726	86.0
Radiology examinations	280	13.9
Others	2	0.1
Total	2008	100.0

86.0% of cases had microscopic confirmation of the diagnosis, either histological or cytological and 13.9% on the basis of radiology examination.

Histopathologic types

In terms of lung cancers, non-small cell carcinoma (NSCC) made up 94.4% and small cell carcinoma (SCLC) comprised the remaining 5.6%. Squamous cell carcinoma was the most common type of lung cancers, representing 35.7% of lung cancers, 37.8% of the NSCC. Adenocarcinoma came a close second at 31.3% of the NSCC. Large cell carcinoma and adenosquamous carcinoma were rare types of NSCC, with the former accounting for 2.5% of the cases and the latter took up 2.9%.

Invasive ductal carcinoma was the predominantly histological presentation (82.5%) of breast cancers and papillary carcinoma was found to be the most common variety in thyroid carcinomas.

There were 1128 patients were assigned cancer stage (56.2%). Among them, 648 patients were presented with a late-stage (over stage III) (57.4%). Lung cancer took the top position with regard to late-stage at 86.8%. This was followed by liver cancer at 68.2%. In terms of early-stage (= stage II), cervix cancer topped the table at 82.6%, followed by thyroid cancer 79.4% and breast cancer 74.8%.

In breast cancer patients: 76.7% of them showed with stage T2 or higher, 58.8% had lymph node metastasis and 12.6% cases of distant metastases at the time of diagnosis.

Treatment modality

Surgery was the first mainstay for treatment of various types of cancer (43.8%), followed by symptomatic and chemotherapy (27.5% and 13.6% respectively). Other treatment methods constituted lower figures.

Comorbidity

Figure 6. Comorbidity

Concerning comorbidities, 9.8% of cancer patients were diagnosed with hypertension. The figures for diabetes type 2 and hepatitis B or C Virus were 3.1% and 8.2% respectively.

0.6% cancer patients were diagnosed with hepatic or kidney failure.
