Cancer survival in Khon Kaen province, Thailand

Abstract

Thailand is one of the few developing countries for which population-based cancer survival data are available. Using clinical follow-up information and reply-paid postal enquiries, 10,333 residents of Khon Kaen province registered with cancer in the period 1985-1992 were followed-up to the end of 1993. The sites of the most common cancers in the province were liver (5-year relative survival rate 9.2%), cervix (60.1%), lung (15.4%), breast (48.1%) and large bowel (41.9%). Results for Khon Kaen were compared with age-standardized survival data for the US and Scotland. Survival was consistently higher for US whites compared to Khon Kaen residents for those cancers whose prognosis is associated with early diagnosis (breast, cervix and large bowel) or the availability of intensive therapy (leukaemia and lymphoma). The main implication of these results for cancer control in Thailand is that the interventions of greatest potential benefit are those designed to promote early detection. More than one-third of all cancers in Thailand are liver tumours: primary prevention through control of hepatitis-B infection and liver fluke infestation is the only effective strategy for their control.

Factors Affecting Survival Time of Cholangiocarcinoma Patients: A Prospective Study in Northeast Thailand

“…In the present study the six-month survival was 35.7 %, while in an earlier population-based study of liver cancer in Khon Kaen the 1-year survival was 28.5% (Sriamporn et al, 1995). Median survival time CCA diagnosis to death was 4.3 months similar to that in a prospective study in 133 CCA patients in Romania (5 months: Mihalache et al, 2010) and in a retrospective study in 69 CCA patients in Malaysia (Yusoff et al, 2012).…”

“…Most cases are clinically silent in the early stages of disease, and are detected at an advanced stage (Blechacz et al, 2008;Mihalache et al, 2010), with a correspondingly poor prognosis. The median survival is about 4-5 months (Mihalache et al, 2010;Yusoff et al, 2012) and one-year survival between 22% and 28% (Sriamporn et al, 1995;Mihalache et al, 2010). Survival time of patients with CCA can be improved by early detection followed by curative resection (Blechacz et al, 2008;Mihalache et al, 2010;Li et al, 2011 patients are eligible for curative surgery (Mihalache et al, 2010;Yusoff et al, 2012).…”

A population-based survival study on female breast cancer in Madras, India

“…Table 3 shows the age-standardized relative survival rates of breast cancer patients from selected registries (with the age distribution of patients in Madras as the reference). The 5-year relative survival from Madras was lower than that observed in European and English registries , US-SEER White and Black populations (Ries et al, 1994), Alberta, Canada (Berkel et al, 1990), New South Wales, Australia (Taylor et al, 1994) and in Bombay, India (personal communication, BB Yeole) and greater than in Bangalore (Nandakumar et al, 1995), Khon Kaen, Thailand (Sriamporn et al, 1995) and Trivandrum, India (Krishnan Nair et al, 1993). The lower survival in Madras than in developed countries could be explained by factors such as lower awareness, lack of screening and other early detection activities, late detection of disease and under availability as well as lack of adequate use of advances in treatment, such as adjuvant therapy.…”

Survival Time and Molecular Subtypes of Breast Cancer after Radiotherapy in Thailand

“…In Thailand, there have been few studies about breast cancer survival and no study about survival after radiotherapy or in terms of biomarkers and molecular subtypes (Sriamporn et al, 1995;Suwanrungruang et al, 2011;Chuthapisithet al, 2012;Poum et al, 2012;Chuangsuwanichet al, 2014). This study aimed to investigate the association between molecular subtypes and survival among breast cancer patients treated with radiotherapy.…”
