11-Oxygenated Androgens Are Biomarkers of Adrenal Volume and Testicular Adrenal Rest Tumors in 21-Hydroxylase Deficiency.
Turcu AF, Mallappa A, Elman MS, Avila NA, Marko J, Rao H, Tsodikov A, Auchus RJ, Merke DP. Turcu AF, et al. Among authors: tsodikov a. J Clin Endocrinol Metab. 2017 Aug 1;102(8):2701-2710. doi: 10.1210/jc.2016-3989. J Clin Endocrinol Metab. 2017. PMID: 28472487 Free PMC article.
CONTEXT: Patients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes. OBJEC …

Prostate cancer in young men: an important clinical entity.
Salinas CA, Tsodikov A, Ishak-Howard M, Cooney KA. Salinas CA, et al. Among authors: tsodikov a. Nat Rev Urol. 2014 Jun;11(6):317-23. doi: 10.1038/nrurol.2014.91. Epub 2014 May 13. Nat Rev Urol. 2014. PMID: 24818853 Free PMC article. Review.
Furthermore, although the majority of men with early-onset prostate cancer are diagnosed with low-risk disease, the extended life expectancy of these patients exposes them to long-term effects of treatment-related morbidities and to long-term risk of disease progres …

Papillary renal cell carcinoma revisited: a comprehensive histomorphologic study with outcome correlations.
Warrick JI, Tsodikov A, Kunju LP, Chinnaiyan AM, Palapattu GS, Morgan TM, Alva A, Tomlins S, Wu A, Montgomery JS, Hafez KS, Wolf JS Jr, Weizer AZ, Mehra R. Warrick JI, et al. Among authors: tsodikov a. Hum Pathol. 2014 Jun;45(6):1139-46. doi: 10.1016/j.humpath.2014.02.004. Epub 2014 Feb 20. Hum Pathol. 2014. PMID: 24767860 Free PMC article.
To address this, we evaluated a cohort of P-RCCs diagnosed between 1997 and 2004 with long-term clinical follow-up data (n = 56). Histomorphologic features previously described in the spectrum of type 1 and type 2 P-RCCs were recorded for each tumor, including nuclear grad …

The role of human epidermal growth factor receptor 2 in the survival of women with estrogen and progesterone receptor-negative, invasive breast cancer: the California Cancer Registry, 1999-2004.
Brown M, Tsodikov A, Bauer KR, Parise CA, Caggiano V. Brown M, et al. Among authors: tsodikov a. Cancer. 2008 Feb 15;112(4):737-47. doi: 10.1002/cncr.23243. Cancer. 2008. PMID: 18189290 Free article.
Negative ER and PR status was associated with an increased risk of death. There was a small but significant difference in both long-term and short-term survival patients who had TN tumors compared with patients who had DN tumors. ...

Time interval to the development of breast carcinoma after treatment for Hodgkin disease.
Wendland MM, Tsodikov A, Glenn MJ, Gaffney DK. Wendland MM, et al. Among authors: tsodikov a. Cancer. 2004 Sep 15;101(6):1275-82. doi: 10.1002/cncr.20516. Cancer. 2004. PMID: 15316904 Free article.
The PHPH regression model revealed that the use of radiotherapy had an adverse effect on long-term survival (relative risk [RR] = 1.84, P = 0.01), but was associated with a short-term survival advantage (RR = 0.45, P = 0.01). CONCLUSIONS: Use of the PHPH model indic …

Two-sample statistics for testing the equality of survival functions against improper semi-parametric accelerated failure time alternatives: an application to the analysis of a breast cancer clinical trial.
Broët P, Tsodikov A, De Rycke Y, Moreau T. Broët P, et al. Among authors: tsodikov a. Lifetime Data Anal. 2004 Jun;10(2):103-20. doi: 10.1023/b:lida.0000030198.06968.98. Lifetime Data Anal. 2004. PMID: 15293627 Free PMC article.
These tests are designed for comparing either the short- or the long-term effect of a prognostic factor, or both. These statistics are obtained as partial likelihood score statistics from a time-dependent Cox model. ...

Semi-parametric models of long- and short-term survival: an application to the analysis of breast cancer survival in Utah by age and stage.
Tsodikov A. Tsodikov A. Stat Med. 2002 Mar 30;21(6):895-920. doi: 10.1002/sim.1054. Stat Med. 2002. PMID: 11870824
A flexible class of semi-parametric survival models is proposed that takes account of long- and short-term covariate effects in cancer survival. The diversity of responses described by the models include non-proportional and crossing survival curves as well as a fraction o …

A survival model for fractionated radiotherapy with an application to prostate cancer.
Zaider M, Zelefsky MJ, Hanin LG, Tsodikov AD, Yakovlev AY, Leibel SA. Zaider M, et al. Among authors: tsodikov ad. Phys Med Biol. 2001 Oct;46(10):2745-58. doi: 10.1088/0031-9155/46/10/315. Phys Med Biol. 2001. PMID: 11686286
It was found that progression time is inversely proportional to dose, which means that patients recurring in higher dose groups have shorter recurrence times, yet these groups have better survival, particularly long-term. The explanation for this seemingly illogical observ …
