My oncologist gave me 2 options for my adjuvant chemo treatment that involve these durgs.  She said she can't decide for me.

Taxotere (T), Cytoxan (C), Adriamycin (A)

1st option: 
T C every 3 weeks × 4

2nd option
 T A C  every 3 weeks x 6
May affect the heart and increases chances of leukemia by 1%. Increases survival rate by 3%.

I had Stage 2A 3.5 cm negative lymph nodes, BRCA negative.
Which one would you choose?

Maybe a second opinion, if possible,  is a good idea if unsure?

Faith,
I was given options and after asking questions, decided together with my oncologist to go with ACT. Cancer diagnosis was my first major health issue so needed guidance from professionals. My team of doctors were commited to me as a person, not as a number. I asked for their recommended course of treatment, especially when there were options on the table, but ultimately it was my decision and I chose to follow their recommendations. They did not decide for me but we worked together as I gathered information about each option. I am so grateful for each one of my doctors and nurses who were caring, kind and professional every step of the way.
Ask questions about each option, then you could ask your oncologist's opinion/recommended treatment based on your individual diagnosis then make your decision based on the information you gathered.
Keep us posted

Faith,

Can you get a 2nd opinion?  When I was diagnosed in 2009, TC (chemo lite) was sometimes given for early stage bc with smaller tumors.  I noticed through the following years, that the standard of care (chemo) was usually AC followed by T or vice versa.  More recently, oncologists are adding Carboplatin to Taxol.  

Is there a reason for TAC together and not sequentially (A/C, then T or vice versa)?  

I haven't noticed that many women getting TC anymore, unless it's a small tumor or if there is a medical condition preventing the women from getting A (Adriamycin).  

I'm wondering why your onc can't decide?   Are there underlying health risks she's concerned about?  I really think another opinion from a different cancer center will make you feel better about your choice of treatment.

I agree with Tamara. I am in Chicago area and my son went thru chemo when he was 10. So when it was my turn i asked the docs what was best and they said Act . i agreed with fhem. I am a total internet fiend so I am a little curious why they didn't suggest carboplatin after seeing so many women doing this on this site.but I will be asking that question at my next appointment

Faith,

A couple of links to look at:

Current treatment strategies

Triple-negative breast cancer

Chemotherapy is the mainstay of adjuvant treatment for patients with triple-negative disease. We consider adjuvant chemotherapy for tumors >0.5 cm or axillary lymph node involvement. For node-positive disease, typically, we would recommend dose-dense AC-T.39 However, TC is a reasonable adjuvant therapy choice for node-negative or low-risk node-positive breast cancer.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4197909/




Sequential AC-weekly paclitaxel or every 3 week docetaxel

The ECOG E1199 trial was designed to identify the optimal taxane and schedule. This trial enrolled 4,954 patients with stage II–III breast cancer who received standard AC followed sequentially by taxane therapy using a 2 × 2 factorial design. The study found no difference in the primary comparisons of taxane (paclitaxel vs docetaxel) and schedule (every 3 weeks vs weekly); other pre-specified analyses included a comparison of the standard every 3 week paclitaxel arm (175 mg/m2) for four cycles (P3 control arm) with weekly paclitaxel (80 mg/m2) for 12 weeks (P1 arm), docetaxel (100 mg/m2) every 3 weeks for four cycles (D3 arm), or weekly docetaxel (35 mg/m2) for 12 weeks (D1 arm) [100]. After a median follow-up of 5.3 years, the P1 arm was associated with improved DFS (HR, 0.73; P = 0.006) and OS (HR, 0.68; P = 0.01) compared with the P3 arm. Although improved DFS was also observed for the D3 arm (HR, 0.77; P = 0.02) without a survival benefit, it was associated with substantially more toxicity than the P1 arm. In an updated analysis after a median follow-up of 12.1 years, DFS was significantly improved and OS marginally improved for both the P1 arm (HR, 0.84; P = 0.011 and HR, 0.87; P = 0.09, respectively) and D3 arm (HR, 0.79; P = 0.001 and HR, 0.86; P = 0.054, respectively). Although weekly paclitaxel improved DFS and OS (HR, 0.69; P = 0.010 and HR, 0.69; P = 0.019, respectively) in triple negative breast cancer, no experimental arm improved OS for hormone receptor-positive, HER2 non-overexpressing breast cancer [101]. Another trial found no difference in outcomes comparing weekly paclitaxel (80 mg/m2 for 12 doses) with biweekly paclitaxel given at a higher dose (175 mg/m2 for six doses) given sequentially after AC, although there was more toxicity with biweekly higher dose paclitaxel schedule [102].

Sequential versus concurrent taxane administration

The NSABP B30 trial addressed the question of whether docetaxel is best given concurrently with or sequentially following doxorubicin [103]. The study included 5,351 patients with node-positive breast cancer to receive four cycles of AC followed by four cycles of docetaxel (sequential AC-D), four cycles of doxorubicin and docetaxel (AD), or four cycles of doxorubicin, cyclophosphamide, and docetaxel (concurrent DAC). After a median follow-up of 73 months, DFS was improved in the sequential-AC-D arm compared with the AD (HR, 0.80; P = 0.001) and the concurrent DAC arm (HR, 0.83; P = 0.01), and OS was likewise improved in the sequential-ACD arm compared with the AD arm (HR, 0.83; P = 0.03) and concurrent DAC arm (HR, 0.86; P = 0.09).

I got a 2nd opinion.  I will now be getting AC every 2 weeks for 4 weeks.  After that , Taxol once a week for 12 weeks.  Thanks for all your comments

Did you mean just two treatments, or did you mean to say four months instead of weeks?
Wish I could just do two treatments of the a/c. I've considered 4 treatments of Taxotere/Cytoxan, but with the knowledge that as many as 15% of patients never get their hair back, I've changed my mind. I know it sounds vain, but I'd rather have a weaker heart than be permanently bald! 
Good luck to you. I'm starting very soon.

My wife had cancer in both breasts, in 2008 and 2016, she had chemo because she had lymph nodes involved, etc, (too complicated to discuss and boor) she had Taxane both time, or Taxotare, it's basically lethal to cancer cells, Taxol , the family, it's called, has a lifetime limit because it can cause heart muscle damage. My wife has exceeded the limit, so if she has any more cancer, she can't have Taxol, because the regimen would put her over the limit. Her hair never grew back after the first time, but I think this depends on the woman's hair-type and age, it grew back except down the middle. Not important to us because she's alive and well now. Taxol cause heart muscle damage and hair loss, not sure if that's clear here. They tell you that. My wife now has a great cardiologist, she developed a condition where she takes "Eliquis" , but it isn't clear if all the chemo was direct result of her heart problem. Maybe the chemo did harm, but what was her choice at the time with Stage 2B-Lobular and Stage 3A-Metaplastic? It runs in her family. The Eliquis is like a time-release blood thinner.
